“Solacium” (Flanagan)
Then recently on one of my periodic trips to New York’s East Village record shops, I was doing my flip-through-the-jazz-bins routine, panning for gold and expecting to turn up nothing but the usual rocks. But then in the Kenny Burrell section, the deep purple of this cover peeked out from the tightly-packed row. I assumed this was another OJC reissue, but when I slid the record out of the jacket I was surprised to see the early ’60s blue Prestige label. Things were starting to heat up. The next crucial step was examining the dead wax. With any luck I’d find the initials of Mr. Rudolph Van Gelder stamped there, and sure enough, I did.
I then examined the vinyl, which looked solid VG+. The price tag made it seem like this one slipped by whatever staff member priced it, and strangely, the numbers on the sticker indicated that it had been priced for sale three months prior. I had to believe that it sat behind the counter for months before it made its way to the racks because this record at this price would never last in a store for more than a week. Finally, I brought it over to the listening station for the final leg of my inspection routine and was humbly blown away by how quiet and clean it sounded. So I didn’t hesitate to bring it to the front and I slammed my cash down on the counter: “It’s a deal.”
In the past I’ve expressed disbelief in the commonly uttered collector sentiment that “vintage jazz records sound better than they look”. But this record wasn’t just providing evidence to the contrary, it was proving me dead wrong. I don’t think I’ve ever encountered a record that looked more marked up and sounded so quiet. In fact, this record sounds cleaner than a lot of records I own that are visually EX.
Recorded in the spring of 1957, we hear John Coltrane in a less adventurous but more accessible mood characteristic of the saxophonist before he began his ferocious onslaught of scales later that year with the release of Blue Train (Blue Note 1577). “Minor Mishap” and “Eclypso” are two favorites, but the ultimate mood-setter is “Solacium”, a somber, quiet tune that will perfectly complement a rainy afternoon spent indoors. Available in bold, straight-down-the-middle Hackensack mono only — no stereo option here.

Selection: “Heavy Dipper” (Morgan)
A while ago I happened upon the YouTube channel of “KoolKatJazz”, a collector who takes pride in finding cheap original pressings of vintage jazz records that, while perhaps grade VG or lower, sound great at times nonetheless. Being a collector on a pretty strict budget made me think that this might be a collecting strategy I could benefit from.
Then I came across this copy of The Cooker. It looked VG at best, and while I would normally pass on a record like this due to a personal intolerance of audible wear and loud pops and ticks, this time I had the opportunity to preview the playback before buying. Indeed, the record had its share of loud ticks and even a skip at one point, but no distortion, and at times the thing sounded undeniably brilliant. The price was more than fair so I decided to go for it.
Though I was originally under the impression that mono issues of this album are quite rare, collecting buddy Clifford Allen informed me that in addition to a West 63rd “R” repressing, mono pressings with New York USA and even United Artists “classic” labels exist. Shout out to Clifford for helping make this article more accurate!

I had never heard these sides before I found this copy. I’m not the biggest fan of the mega-standard “A Night in Tunisia” and accordingly was a little underwhelmed by this epic reading. But just as I began to fear that the date would ultimately amount to no more than “another bop blowing session”, Pepper Adams’ quirky presence grew on me, and I soon came to appreciate this pleasantly odd frontline pairing of trumpet and baritone sax. Prior to the release of The Cooker, Morgan had never laid to tape any of his own compositions, and thus with “Heavy Dipper” and “New Ma”, the world got its first glimpse of the leader’s talents as a songwriter. And most collectors will be able to appreciate the magic contained in these fresh 1957 mono Plastylite grooves.

Selection: “Light Blue” (Monk)
1. Some of Monk’s most inspired recordings were for Blue Note in the late ’40s and early ’50s. As a result, they are not high-fidelity and I don’t find myself seeking out older recordings like this on vinyl.
2. Though Monk’s recordings for Prestige are generally of outstanding quality in terms of both fidelity and performance, the sequencing of these recordings for Monk’s Prestige LPs is scattered in comparison to the original 10″ LP sequences, which make more sense to me.
3. I enjoy many of Monk’s Riverside releases but I’ve never found vintage Riverside pressings to be of a very high quality. I’ve owned a few but resold them shortly after acquiring them.
4. Much of Monk’s output for Columbia included songs he had already recorded for other labels in the past, and in most cases I prefer the older recording. No doubt, Monk’s Columbia recordings are of exceptionally high fidelity, but I do find that his playing on older albums sounds a little more inspired. I also don’t feel that the pinpoint accuracy of the Columbia recordings suits Monk’s music as well as the sonic signature of studios like Hackensack (Prestige and some Riverside) and Reeves (Riverside).
One of the exceptions to 4. above is this compilation of previously unreleased live material. Knowing that Monk felt his studio albums primarily served as advertisements for his live performances, I’ve taken a stronger interest in the pianist’s live albums. Although this album was released relatively close to the death knell of mono in 1964, and despite the fact that Columbia had been releasing brilliant-sounding stereo LPs for several years by that time, I still cherish the mono version of this album because the stereo mixes of Monk on Columbia fail to position the leader in the center of the stereo field.
This album has sentimental value to me because it served as my introduction to Monk when I borrowed my friend’s copy many years ago and this is the second original mono copy I’ve owned. The first was in pretty good shape but last year at the WFMU Record Fair I stumbled upon this copy in near-new condition, and for the asking price I couldn’t pass it up.
Vinyl Spotlight: Hank Mobley with Donald Byrd and Lee Morgan (Blue Note 1540) Toshiba Reissue
- Japanese Toshiba reissue circa 1983 (BN 1540)
Personnel:
- Donald Byrd, trumpet
- Lee Morgan, trumpet
- Hank Mobley, tenor saxophone
- Horace Silver, piano
- Paul Chambers, bass
- Charlie Persip, drums
Recorded November 25, 1956 at Van Gelder Studio, Hackensack, New Jersey
Originally released January 1957
Selection: “Touch and Go” (Mobley)
Selection: “Double Whammy” (Mobley)
There was something different about this sound, though. The horns had a tremendous sonic impact. The unique arrangement of two trumpets and one tenor saxophone was certainly playing a role, but recording engineer Rudy Van Gelder had clearly found a rare synergy with his equipment that day and I have yet to hear this horn sound topped by any other jazz recording. It is intense, smooth, and cohesive all at once. Van Gelder was getting a similar sound on other albums in late 1956 but perhaps the particular combination of Mobley, Byrd, and Morgan sets this album apart. The engineer’s choices regarding microphone positioning, preamplifier gain, compression, and instrument balance certainly played a role in the creation of this monumental sound as well.
The album’s compositions, all written by leader Hank Mobley, are consistently menacing. The haunting harmonies of “Touch and Go” and “Double Whammy” carry a sense of foreboding, and while “Barrel of Funk” has a rather upbeat “A” section, the tune ultimately transforms into an intriguing progression of minor-key origins at its bridge. Even the album’s most upbeat tune, “Mobleymania”, manages to keep listeners on the edge of their seats with harmonic tension.
Blue Note catalog number 1540 features Mobley’s characteristic sweet, smooth tone throughout. As a youthful pair of trumpeters, Donald Byrd and Lee Morgan are difficult to tell apart. Horace Silver does little to detract from this star-studded frontline, and the forefather of bop humbly yet tastefully blends into the background for much of the program. Silver’s comping is never boastful here, but at the same time it falls short of embodying the pianist’s big musical personality and signature funk (it wouldn’t be long before Silver would ditch sideman work for good and become the leader of his own legendary quintet). To round things out, drummer Charlie Persip sits at the throne behind his drum kit in the far corner of Rudy Van Gelder’s living room studio. I cannot get enough of the beautiful simplicity of Van Gelder’s mono drum sound at Hackensack in the late ’50s. Persip sounds just as good as anyone in that room and his straight-ahead timekeeping compliments Van Gelder’s technique exceedingly well.
Beyond a repress in the late ’60s after Blue Note had been sold to Liberty Records (the proof of which lies in the existence of copies with “RVG” etchings but no “ear”), this album has never been reissued in the United States, not even on compact disc (it has, however, appeared on numerous compilations including Mosaic’s box set of Mobley’s ’50s Blue Note recordings). The Japanese almost never left a Blue Note stone unturned though and this album is no exception, having been reissued by Toshiba-EMI five times in various formats. I was also considering the King reissue from the same year when I bought this 1983 Toshiba copy on eBay from a Japanese seller but ultimately chose the Toshiba not only because it was cheaper but I also noticed that the fonts used on the Toshiba cover more accurately portrayed those of the original artwork (King album covers also often admit an unnaturally high level of contrast). This was my first Japanese Blue Note vinyl reissue venture and I remember being stunned by how dead-quiet this pressing was.
My dream is to someday own a vintage copy of this album with RVG etchings. Until then, this Toshiba reissue is sure to get lots of turntable time in my house.
Vinyl Spotlight: Reflections: Steve Lacy Plays Thelonious Monk (New Jazz 8206) OJC Reissue

Selection:
“Reflections” (Monk)
On this expedition I had the luxury of being able to preview records as I dug, and when I put this record on I was surprised by how much I liked what I was hearing. I quickly realized that Lacy had chosen more obscure, challenging Monk tunes for the album. Wynton Marsalis did something similar when I saw the Lincoln Center Jazz Orchestra pay tribute to Monk at Town Hall in New York City in 2016 and I admire the bravery that goes into making this kind of choice.
Not to discredit Lacy’s chops (of which he has plenty), just the combination of Monk’s music being played with soprano sax is a treat in and of itself. Lacy and session pianist Mal Waldron are clearly big fans of Monk’s, each having recorded Monk tunes numerous times throughout their careers. Considering how much I enjoy this album on top of its condition and the price I paid, this has become one of my favorite records in my collection.

Selections:
“Pumpkin” (Hill)
“Black Fire” (Hill)
First and foremost, I think this is one of the greatest album covers of all time. I love the juxtaposition of the bold strips of various red hues with the cartoony black-and-white illustration of fire beneath. Reid Miles’ cover design speaks volumes and yet again complements the music incredibly well.
From the time Andrew Hill arrived at Blue Note in 1963, it didn’t take long for the pianist-composer to venture “out” and away from bop. Hill first recorded for the label in September of that year with Joe Henderson (Our Thing, Blue Note 4152), then with Hank Mobley the following month (No Room for Squares, Blue Note 4149). Black Fire, Hill’s first album as a leader for Blue Note, was recorded in November 1963 and gives us an early glimpse at Hill loosely conforming to the higher degree of harmonic and melodic structure commonly found in bop. Blue Note would continue to document Hill’s musical explorations in the coming months, laying to tape Smokestack, Judgment!, then finally Hill’s avant-garde classic Point of Departure in March 1964 — the same month that Eric Dolphy recorded his landmark album Out to Lunch! for the label.
This album is about as far out as I’m willing go into the free jazz sea. I’m not a fan of free jazz and don’t know much about it, but from the little I do know I’m willing to say that Black Fire tows the line between post bop and the avant-garde. The sounds here tend to invoke a subtle feeling of panic, but much like another favorite mid-sixties quartet album of mine, Black Fire maintains a surprising degree of calm and quietude through all of the chaos. We also get to hear Roy Haynes on an uncommon Blue Note date and he doesn’t disappoint, demonstrating his patented pinpoint precision and tight snare drum work throughout.

My Friday Night copy is considered an original pressing by most collectors but my Saturday Night copy is not due to the “CBS” marking on the labels. This is where I diverge from the record collecting consensus. I would agree that the CBS copy is not a first pressing but I would argue that there’s nothing wrong with referring to it as an “original pressing”. Being as specific as possible seems the honorable thing to do when it comes to selling, but my feeling is that in everyday conversation any copy of an album that would have been released in the era the album was originally released can rightfully be called an original (certainly, “in the era” is open to interpretation). Seeing that my CBS copy of Saturday Night was in all likelihood pressed in either the same year or the year after a first pressing, I don’t hesitate to think of this as an “original pressing”.
Live recording is by and large a more challenging endeavor when compared to the higher degree of control typically obtained in a recording studio. That being said, this Miles Davis album is an exceptional example of a live recording. Every instrument has its own space, even in mono, and the level of detail and accuracy here is a welcome break from the smeared, distorted sound of many live albums. Not only does Jimmy Cobb’s drum kit sound incredible here, his playing has a captivating and energetic sense of forward motion that seems to predict Tony Williams’ inclusion in Davis’ lineup shortly after. These albums also present a rare opportunity to hear how tenor saxophonist Hank Mobley, a mainstay of Blue Note records, holds up under the intense scrutiny of the date’s superstar bandleader.

Originally released November 1964
Selections:
“One Finger Snap” (Hancock)
“Oliloqui Valley” (Hancock)
This is one of my favorite Herbie Hancock albums. It has a soft, gentle vibe that I return to time and time again when I want to listen to something quiet. The quartet with trumpet seems like the perfect minimal arrangement for this album, and even though I’m not the biggest Freddie Hubbard fan, I find that he fits in with the rest of the group like a glove here. I love the cover too. Reid Miles had a way of making album art reflect the music contained within, and with this album, the simple, out-of-focus image of shimmering water cast in a teal blue tint complements the music extremely well…even the pronunciation of the title has a calming sort of effect (“Em-PEE-ree-in”).
Although the album’s closing track, “The Egg”, ventures out a bit too far for my taste, the other three compositions are all favorites. “Cantaloupe Island” sounds like part three in a trilogy of soulful, radio-friendly Hancock compositions that began with “Watermelon Man” and “Blind Man, Blind Man”, but side 1 consists of sixteen of my favorite minutes in music. Eighteen-year-old (Eighteen!) Tony Williams’ drumming is fiery, imaginative and expressive. His kit sounds incredible here as well, especially his ride cymbal. Engineer Rudy Van Gelder’s spacious Englewood Cliffs studio had a way of making drum kits sound colossal when they needed to, which can be heard during Williams’ solo on “One Finger Snap”. Who would have ever thought that Blue Note darling Freddie Hubbard would pair with the rhythm section of Miles Davis’ Second Great Quintet so well?

“Blue Shoes” (Fuller)
Truth be told, these United Artists mono pressings from the early to mid ’70s are hit and miss, having heard more than one that suffered from significant non-fill problems. But this particular copy made it through that inconsistent manufacturing process unscathed. United Artists pressings also seem to have a gentler top end than a lot of modern audiophile reissues, which to some collectors makes them worth seeking out despite the difficulty in finding a quality copy.
This particular Cliff Jordan album also seems difficult to find in any format, which is why I jumped at the chance to buy it when it popped up on eBay. Discogs indicates that it has only been issued in the US twice on vinyl (originally in 1957 and this copy in the early ’70s) and never on CD. Though it has been reissued by Toshiba EMI in Japan once as an LP in 1984 (undocumented by Discogs) and three more times on compact disc there, these copies are hard to find in the states. And try you may, but you will not find these sides in any shape or form on iTunes or Spotify, making this a rare and special listen indeed.
Mono Vinyl Playback on a Modern Stereo Audio System

For someone who grew up in the stereo age, mono recordings can sound primitive and cramped when compared to the wider, more spacious aspects of stereo sound, and this heightened sense of realism is what ultimately won over the music-buying public back in the 1960s. But not only are some of history’s greatest music performances only available to us as mono recordings today, time has proven that the antiquated format possesses an allure that continues to charm music lovers of all ages. When done right, mono recordings demonstrate a great sense of cohesion and power, and the best of them also do an ample job of establishing a sense of depth and space. Though creating a mono recording that checks all of these boxes is no small technological feat, the great audio engineers of yesteryear have managed to hand down to us a treasure trove of work in mono that is both breathtaking and timeless.
If you’re a vintage jazz record collector, you’re probably aware of the fact that all mono LPs are compatible with today’s stereo audio equipment. While this is true, playing a mono record on a stereo audio system without making the proper adjustments leaves room for improvement. This article is designed to help you get the most out of playing your mono LPs in a modern stereo world.
What Exactly Is a Mono Record?
The answer to this question is potentially quite complicated. The difference between mono recordings and mono masterings of recordings needs clarifying, as does the difference between mono records cut before and after the death of the mono format in the late 1960s. For the purpose of this article though we can settle for a simpler definition of a mono record being a record that is intended to produce the same exact audio signal in both the left and right channels of a stereo audio chain. True, without any fuss a listener will hear roughly the same thing coming from both speakers when they play a clean mono record on a stereo audio system (think reissues), but our goal is to hear the exact same thing from both speakers and in the process lower distortion and improve the signal-to-noise ratio of the overall listening experience. This goal becomes especially important when dealing with original pressings made in the 1950s and 1960s that have accumulated a significant amount of wear from usage.
Knowing If a Record Is Mono
Before we get started, let’s be sure that our records are even mono in the first place (by all means, if this is a no-brainer for you, feel free to skip this section). The easiest way to tell if a record is mono is if there is some indicator on either the front or back of the album jacket. For vintage records (we’re still talking ’50s and ’60s), the absence of the word “stereo” will usually suggest that a record is mono. The next easiest way to tell is simply by listening, and the best way to achieve this goal is with headphones. If the music sounds mono (like it’s in the center of the stereo field) but the surface noise sounds stereo (wider in the stereo field), your record is mono. Note that the loudest parts of a mono record are where you will hear the first signs of distortion from wear, and at those moments the music may sound like it’s stereo (though it shouldn’t), so focus on quieter parts of the music. Finally, to state the obvious, if there are instruments or sounds distinctly positioned to either the left or right side of the stereo spread, your record is stereo. In cases where the stereo positioning of instruments is more extreme — common in our era of the ’50s and ’60s — you can also easily identify a stereo record by turning the panning knob on your amplifier all the way left then all the way right and back again. If some instruments sound very present at one turn then very distant or completely absent at another, then your record is stereo.
What’s Wrong with Listening to a Mono Record in Stereo?
If you’ve been listening to mono records in stereo your whole life, there are two significant ways in which your listening experience can be improved by effectively listening in mono on a stereo system. First, surface noise can be reduced and made less noticeable. Many marks on the surface of a vinyl record manifest as out-of-phase noise on the far left and right of the stereo field. When listening to a mono record on a stereo audio system, these pops and ticks are heard in a very different position than the actual music, which lies directly in the center of the stereo field. By listening in mono though, not only does the out-of-phase nature of this noise lead to its reduction in relation to the volume level of the music, much of whatever surface noise remains will be masked by the music in the center of the would-be stereo field.
Presented here are two audio clips. The first is of a mono record being played in stereo, the second being the same record played in mono. In the second clip, notice how the surface noise has collapsed to the center of the “stereo field” and is more difficult to discern once the music kicks in:
Horace Silver, “Finger Poppin'” (Original 1959 mono pressing of Finger Poppin’ with the Horace Silver Quintet)
Stereo Playback:
Mono Playback:
Second and similar to surface noise, groove wear on vintage mono records also often manifests as out-of-phase (stereo) noise. This distortion can also be reduced by listening in mono, and the fuzzy, smeared sound that would be heard listening in stereo becomes a tighter, more focused central image. The following audio clips emphasize this type of improvement:
Lou Donaldson, “Avalon” (Original 1962 mono pressing of Gravy Train)

For a visual account of these improvements, the following two diagrams illustrate how listening to mono records in mono can provide an improved listening experience (the circles represent music and the curved lines represent surface noise):

How Do I Play My Mono Records in Mono on a Stereo System?
Now that we’ve identified the ways in which playback of your mono LPs can be improved, how do we achieve this? Everyone has different equipment situations so there is no one-size-fits-all solution, but surely there is a sensible option for everyone.
If you use a turntable with a tonearm that accepts removable headshells, the most obvious hassle-free solution is to acquire a mono cartridge. Luckily, getting a mono cartridge doesn’t mean you need to hunt down a vintage one. Cartridge manufacturers like Ortofon, Grado, Audio-Technica, and Miyajima all currently provide quality mono cartridge solutions that are compatible with modern stereo turntables.* You may need to adjust your counterweight each time you switch, but when you want to play a mono record, simply swap cartridges. (Click here to visit the Deep Groove Mono Cartridge Database.)

A sampling of mono cartridges currently on the market
If you don’t have a tonearm that uses removable headshells, or if you simply don’t want to fuss with swapping the cartridge and adjusting the counterweight every time, there are other options. While a mono cartridge will produce identical signals in both channels of a stereo system (a duplicated “mono signal”, if you will), simply summing the left and right channels of a stereo cartridge can actually produce comparable results (for more information, see the appendix at the end of this article).
One way to do this is with a mono button on an amplifier. Many vintage stereo amplifiers have mono buttons. If you don’t have access to one of these vintage amps, you can also sum with a stereo-mono switch, though these can be hard to find and are usually custom-built (members of the Steve Hoffman Forum can purchase one here). Another summing option is using a “double Y-cable” configuration, which involves placing a pair of RCA adapters in the signal chain, though the obvious drawback of this option is that you need to remove the adapters every time you switch between mono and stereo (the method is outlined here in this Steve Hoffman Music Forum thread).
Will either using a mono cartridge or summing provide more favorable results? Though the answer to this question certainly depends on which cartridges you are using, here we offer up one of these comparisons. The first is the result of playing a vintage mono record with a Grado MC+ mono cartridge and the second is a clip of the same record being played with a Shure M44-7 stereo cartridge and the mono button engaged on an integrated amplifier:
Johnny Coles, “Jano” (Original 1964 mono pressing of Little Johnny C.)
Grado MC+ mono cartridge:
Shure M44-7 stereo cartridge with channels summed:
A final, less popular option is to use a “left channel only” or “right channel only” setting on an amplifier. Unlike a mono setting that sums the channels, these settings will duplicate one of the two stereo channels in both signal paths. While this method typically fails to improve the signal-to-noise ratio of the signal, it is preferable in some rare instances. For example, if a record was played many times on a turntable with severe anti-skate problems, one groove wall may be in much better shape than the other, and listening to one channel or the other may prove more desirable than summing.

Vintage vs. Modern Mono Records & Stylus Size: Is Bigger Always Better?
The only other variable that modern mono lovers need to consider is stylus size. Today’s stereo (and mono) LPs are cut with a groove width optimized for playback with a modern stylus tip measuring approximately 0.7 mils at its longest radius (1 mil equals 0.001 inches or one-thousandth of an inch; in the metric system, 0.7 mils is equivalent to about 18 “microns” or micrometers, where 1 micron equals 0.001 millimeters or one-millionth of a meter). However, vintage mono LPs mastered prior to 1970 were actually cut with the intention of being played back with a larger 1-mil (25-micron) stylus.
For mono LPs mastered after 1970, a 0.7-mil stylus is the only sensible option. Fortunately, this is the spec for virtually all modern cartridges, mono and stereo alike (a few exceptions to this rule are the Ortofon OM cartridge with optional D25M stylus, the Ortofon CG 25, and the Miyajima Zero, all which sport 1-mil styli). As for playback of vintage mono LPs mastered before 1970, while it’s true that these discs were cut to be played with a 1-mil stylus, a 0.7-mil stylus will also fit these grooves. What’s more, there’s an attractive theory that a narrower 0.7-mil profile might avoid areas of wear higher up on the groove wall created by repeated plays back when 1 mil was the standard. In a perfect world, collectors would have both options at their disposal and make their choices on a case-by-case basis. But in the event that you must choose one stylus for playback of all mono and stereo LPs from all eras, a 0.7-mil stylus should suit you just fine.

Once more, we have two audio clips to offer up for comparison. The first is a vintage mono LP from 1959 being played with the previously mentioned Ortofon OM cartridge and D25M 1-mil conical stylus, and the second clip is the same record being played with a Shure M44-G cartridge with a 0.7-mil conical stylus (both cartridges are stereo and channels are summed for both clips):

Note that stylus size in and of itself has no bearing on whether a record will play mono or stereo; the inner workings of the cartridge are what ultimately determine this.
Conclusion
Despite stereo’s current reign as the industry’s standard format, mono sound has certain qualities that distinguish it from stereo and make it special. When done right, mono can be a highly enjoyable listening experience. Mono recordings have a simplicity that give them character. Their “punch” is intrinsically tied to the limitations of the format, and the same can be said of the way the elements of a mono mix meld together into one cohesive whole. My hope is that this article has explained how to get the most out of your mono records and has also provided you with a practical, affordable solution in your quest to obtain the finest mono vinyl playback possible.
* Advanced collectors will appreciate a note regarding the difference between single-coil and dual-coil mono cartridge design. In theory, a single-coil design will provide an even higher signal-to-noise ratio than a dual-coil design. Known single-coil models include the Ortofon CG 25, Miyajima Zero, and Denon DL-102. Additionally, mono carts with no vertical compliance (the CG 25 and Zero) may also produce superior results, though newcomers should be aware that the lower compliance of these cartridges requires a special high-mass tonearm to achieve the appropriate resonant frequency for the system.
Appendix
“Stereo information” in a stereo record is information that is not equally present in the left and right channels of a stereo signal, and it is determined by the unique vertical modulations cut into each groove wall. “Mono (centered) information” is equally present in both channels and is determined by horizontal modulations in the groove only. Since surface marks on a record generate both horizontal and vertical motions of a stylus, playing a mono record with a stereo cartridge will not only reproduce noise related to the vertical motions of the stylus, that noise will usually be more noticeable because it will be in a very different position than the music in the stereo field. Using a modern mono cartridge will certainly cure this ailment, but summing a stereo signal from a stereo cartridge will produce noticeable improvements as well. The reason for this is because much vertical noise in a record’s groove is “out-of-phase”, meaning that the voltages produced by the cartridge’s left and right channels are to some extent polar opposites of each other, so when they are summed together, not only is the volume of this (stereo) noise reduced, the relative volume of the mono information i.e. the music is slightly boosted as well.
To illustrate this, the screenshots below show various waveforms in a digital audio workstation. The first shows the left and right channels of a mono record being played in stereo, while the second shows the same record played with the left and right channels summed using the mono button on an amplifier (both clips use the same stereo cartridge):
