There are two entirely honest ways to describe the Vemuram Jan Ray, and they cannot both be the first sentence of an article.
The first: it is one of the most quietly influential overdrives of the last fifteen years, a hand-built brass box from a small Tokyo workshop that ended up under the feet of Michael Landau, Doyle Bramhall II, Mateus Asato, Yvette Young and a Guns N’ Roses guitarist, and which turned an unknown Japanese brand into a name that gets whispered the way people whisper “Klon.”
The second: it is a Paul Cochrane Timmy with a different op-amp, a slightly different treble corner frequency, and a price tag roughly three times the original’s — sold with marketing copy about years of research into vintage Fender amplifiers that never once mentions the Tennessee builder whose schematic it resembles.
Both of those sentences are supported by evidence. Neither of them is the whole story. And the strange, slightly uncomfortable truth about the Jan Ray is that the pedal is genuinely, demonstrably excellent and the ethical objection to it is genuinely, demonstrably reasonable. Most gear writing picks a side and pretends the other one doesn’t exist. We are not going to do that.
What follows is what the Jan Ray actually is, where it came from, who is documented using one, what its four knobs and one hidden screw actually do, how it stacks up against the pedals it gets compared to, and — with the receipts laid out — how to decide whether $388 of brass belongs on your board.
The short version
The Jan Ray is a low-to-medium-gain, broadly transparent overdrive in a solid brass enclosure, hand-built in Tokyo by Vemuram, a brand operated by Tri-Sound Inc. It has four knobs — Volume, Gain, Bass, Treble — and a fifth control, a Saturation trimmer, hidden inside the enclosure and reachable with a small screwdriver. It draws about 5 mA, runs on a 9-volt battery or a standard centre-negative 9 V supply, is true bypass, and weighs 428 grams, which is roughly three times what a comparable aluminium pedal weighs.
Vemuram’s own pitch is that it captures the tone of a cranked mid-1960s blackface Fender amp — specifically the setting guitarists call the “Fender Magic 6.” Whether it does that, whether the circuit is original, and whether the price is defensible are three separate questions, and this article answers them separately.
Where Vemuram came from
A brand that only makes one kind of pedal
Vemuram launched in 2008 in Tokyo under the parent company Tri-Sound Inc., with premises in Chiyoda City. It is unusual among boutique brands in that it has never diversified. There is no Vemuram delay, no Vemuram reverb, no Vemuram compressor. The entire catalogue is gain: overdrive, distortion and fuzz. Everything else — modulation, time-based effects, utility — has simply never been attempted.
That focus explains a lot about how the company behaves. When a brand’s whole identity rests on maybe eight or nine circuits, each one gets iterated on for years, gets an internal trimmer so the customer can fine-tune it after purchase, and gets built in a housing that costs more than the electronics inside it.
The name, and a conflict in the record
The story behind the name is charming and is repeated consistently: the founder’s surname, Uemura, was routinely mispronounced as “Vemura” while he was living overseas, and the final “M” was borrowed from his given name, Masaki. Uemura’s brother was active in the New York live scene, which is how the first pedals reached American session players, which is how the word spread.
Here is where honesty requires a footnote. English-language brand write-ups name Masaki Uemura as founder and CEO alongside an engineer credited only as “Mr. Tezuka.” A separate, well-maintained wiki entry lists the founder/CEO as Shingo Hirano. These are not necessarily in conflict — companies change chief executives, and a founder can step back — but we could not resolve it from a primary source, because vemuram.com is a JavaScript-driven site whose product, artist and FAQ pages return empty templates to any non-rendering fetch. If you have seen the Vemuram site and wondered why almost nobody quotes it directly, that is why. Take the etymology as solid (it is too specific and too consistently reported to be invented) and treat the current executive line-up as unconfirmed.
Why brass
Every Vemuram enclosure is machined from solid brass. The company’s stated reason is shielding: brass is a decent electromagnetic screen and the housings are heavy enough to be mechanically dead. There is also an unstated reason, which is that brass looks like nothing else on a pedalboard and ages into a warm patina, and a brand with nine products needs a visual signature.
The tonal claim sometimes attached to brass — that the enclosure material audibly changes the sound of a solid-state circuit — is not supported by anything measurable. Brass is an excellent material for a trumpet because a trumpet’s body is the resonator. It is not the resonator in an op-amp overdrive. Buy the Jan Ray for how it sounds, not for the metallurgy; but do note that 428 grams of brass with gold-plated jacks is a genuinely different ownership experience from a folded aluminium box, and that difference is not nothing.
“Fender Magic 6”: the story on the box
The Jan Ray’s marketing has always centred on one idea: the punchy, clear, slightly-breaking-up sound of a 1960s blackface Fender combo pushed to the edge. Among Fender players there is a long-standing set-and-forget starting point sometimes called the Magic 6 — volume and tone controls arranged so the amp sits right at the threshold where clean turns to grit without ever getting woolly. It is the sound of a Deluxe Reverb at a volume that will get you thrown out of a rehearsal room.
As a description of what the pedal does, it is fair. The Jan Ray’s voicing is bright-leaning and open in the low mids, it does not hump the midrange the way a Tube Screamer does, and at low Gain settings with the Volume up it does the thing blackface amps do: it gets louder and firmer without getting thicker. If you have ever pushed a clean amp with a boost and wished it stayed clear as it got dirty, that is the Jan Ray’s central trick.
If you want the amp-side version of that same target, the Universal Audio UAFX Dream ’65 chases the identical reference point from the other direction, and a real small-format Fender like the Pro Junior IV gets you into blackface-adjacent territory for less than the pedal costs.
As a description of where the circuit came from, though, the marketing has a problem.
The Timmy question
This is the part of the Jan Ray story that everyone knows about and most reviews skate past in one sentence. It deserves more than that, because the details matter and because the conclusion is less simple than either side claims.
What Paul Cochrane built
Paul Cochrane, working out of Murfreesboro, Tennessee, released the Tim in the early 2000s and the simplified Timmy in 2004. The Timmy’s design goal was transparency in a specific technical sense: enhance the guitar-and-amp relationship rather than impose a voice on it. The circuit is a dual op-amp topology with soft clipping via four 1N4148 diodes in the feedback loop of the first stage.
Its genuinely original idea was the placement of the EQ. The bass control sits before the clipping stage, so low frequencies are trimmed before they can muddy the distortion; the treble control sits after clipping, so highs can be shaped without altering the character of the drive itself. Both were originally cut-style — counterclockwise gave full response, clockwise attenuated. That layout is now so standard in the transparent-overdrive category that it is easy to forget somebody had to think of it first.
Cochrane also declined to behave like a business. No website, no social media, no marketing, months-long waiting lists, and pricing that stayed reasonable the entire time. We covered the mass-market version of his circuit in our MXR Timmy article — that one is an official collaboration, with Cochrane’s involvement and his compensation, and it is the cleanest way to buy this circuit today.
What circuit analysis found in the Jan Ray
Independent teardowns and schematic comparisons — the earliest widely-circulated ones date to 2015, on DIY pedal blogs — concluded that the Jan Ray is the Timmy circuit with a small number of component changes. The differences most often cited are:
The op-amp. An LM4558 in place of the Timmy’s JRC4559 (later versions of the Timmy have also used LM1458). This is a chip substitution within the same broad family, not a different topology.
The treble control’s corner frequency. Roughly a 2.8 kHz rolloff versus the Timmy’s 10.6 kHz. This is the one change that is actually audible as a voicing decision rather than a parts-bin decision, and it is a meaningful part of why the two pedals do not sound identical at matched settings.
The enclosure. Brass, versus a powder-coated Hammond box.
To be precise about what that does and does not establish: a circuit-level resemblance this close is not a matter of opinion once schematics are side by side, and the people who did the work published theirs. But “same topology with changed values” also describes a very large share of the overdrive market, including a good deal of what the Timmy itself descends from. The Timmy family tree includes the Greer Lightspeed, which openly credits its influences; the Walrus Mayflower; several Lovepedal circuits whose provenance the company initially denied and later conceded; and an enormous quantity of budget clones.
So what is the actual objection?
The objection is not that Vemuram used a known topology. Almost everyone does. The objection is the combination of three things: a circuit that closely tracks a specific living builder’s design, marketing copy that frames the result as the outcome of original research into vintage amplifiers, and a price roughly three times what that builder charged for the original. Any one of those on its own is unremarkable. Together they are what generated years of pedal-forum anger and what put the Jan Ray into the same conversational category as the pedals people argue about on principle.
Vemuram has not, to our knowledge, published a response addressing the circuit-analysis claims directly, and we could not find one. That silence is itself part of why the story has never gone away.
How a buyer should actually think about this
Three practical points, stated plainly.
The pedals do not sound the same. Reviewers who have owned both consistently report the Jan Ray as having more gain on tap and a brighter, harder-edged voice, with the Timmy’s upper switch position being the closest match. That is what you would expect from a treble corner nearly two octaves lower and a different chip. “Essentially the same circuit” and “you can hear which is which” are both true.
The Jan Ray is more expensive per unit of tone than anything else in its family. At the time of writing the Jan Ray is $388 new and the officially-sanctioned MXR Custom Shop Timmy is $145 from the same retailer. If your goal is this circuit’s sound, the honest recommendation is to try the $145 version first. If it does what you need, you have saved $243 and paid the original designer.
If the ethics bother you, that is a legitimate reason not to buy it. You do not need to construct a tonal argument to justify a moral preference. Plenty of excellent players have looked at this situation and bought a Timmy. Plenty of other excellent players have looked at it, shrugged, and kept the Jan Ray on the board for a decade. Both are defensible positions and the pedal community has been having this argument long enough that nobody is going to win it.
Specifications
A spec conflict worth knowing about. Vemuram’s published figure and every major retailer’s listing say 5 mA. One widely-syndicated aggregator FAQ says “approximately 10 mA” in the same page where its own key-features list says 5 mA. Either number is trivial for any modern power supply, so this has no practical consequence — but it is a reminder that auto-generated product FAQs on aggregator sites are not sources, even when they sit two inches below correct information.
The controls, decoded
Volume
Unusually powerful, and this is one of the Jan Ray’s real advantages over cheaper pedals in the category. There is a great deal of output on tap — enough to slam the front end of a valve amp hard from a low Gain setting, which is how a large share of the pedal’s professional users actually run it. Owners repeatedly describe the volume control as “behaving like an amp,” meaning you can sit at low gain and high volume and let the amplifier supply the compression.
The practical consequence: unity gain arrives earlier than you expect. If you are setting the pedal up as an always-on, start with Volume around ten o’clock, not noon.
Gain
Runs from genuinely clean boost at the bottom to a medium crunch at the top. It never becomes a distortion pedal and it is not trying to. The useful range for most players is the bottom third to the middle: below nine o’clock it is a transparent lift, around eleven to one it is the classic edge-of-breakup blackface voice, and past three o’clock you get a thicker, more compressed sound that some players like and some find is the point where the pedal stops being transparent.
Bass and Treble
The Jan Ray’s EQ inherits the pre-clipping bass / post-clipping treble arrangement described above, which means the two controls do fundamentally different jobs. Bass is a shaping decision made before the distortion happens — turning it down does not just remove low end, it changes what the clipping stage is given to work with, tightening the note attack. Treble is applied afterwards and is closer to a conventional tone control.
In practice this means: fix your Bass setting first, by ear, with the guitar and amp you actually use, and then use Treble as the final adjustment. Doing it the other way around means re-doing the Treble every time you touch Bass.
The Jan Ray’s Treble is voiced considerably darker than the Timmy’s — that 2.8 kHz corner — which is why it can tame a bright Stratocaster into a Fender amp better than its cousin, and why some players find it harsh in the upper mids where a Timmy stays smooth. Which of those two things you experience depends almost entirely on your pickups.
The Saturation trimmer
This is the control that divides opinion most sharply, and it is the reason two people can own the same pedal and describe two different pedals.
Inside the enclosure is a small trim pot that adjusts the overall saturation and harmonic character of the circuit. Fully clockwise, owners describe it as woolly and thick to the point of muddiness. Fully counter-clockwise, thin and bright. From the factory it sits somewhere in the middle, and a great many owners never move it at all.
The case for it: it lets you match the pedal to your pickups rather than the other way round. Single-coil players and humbucker players genuinely want different amounts of saturation from a low-gain drive, and most pedals resolve that by picking one and hoping.
The case against it: you need a jeweller’s screwdriver, you have to open the pedal, you cannot adjust it with your foot, and once you know it exists you may spend more time fiddling with it than playing. One reviewer’s blunt summary — that Vemuram’s trimmers add a layer of option paralysis — is a fair description of the failure mode.
Practical advice: set it once, deliberately, in a session where you are not trying to write anything. Start at the factory position, note where the slot points, and move it in small increments with your usual guitar and amp. Then leave it alone for a year.
Famous players: what the evidence actually shows
The Jan Ray has one of the more genuinely impressive documented rosters in its price bracket — this is a pedal that spread through the professional session world by word of mouth before it had any marketing at all. But rosters attached to expensive boutique pedals are exactly where bad sourcing accumulates, so here is what we could and could not confirm.
Documented by photograph or video of the actual board
Mateus Asato is the single most important name in the Jan Ray’s story. The Brazilian guitarist posted a photograph of a three-pedal board with the Jan Ray on it, and his association with the pedal was significant enough that Vemuram built him a signature version. In several markets — Korea especially — the Jan Ray’s reputation was effectively established by Asato’s use of it.
Michael Landau is visible with a Jan Ray in the lower right of a pedalboard photograph published by Gearphoria. Landau’s relationship with Vemuram runs deeper than one pedal: the Butter Machine distortion is his signature model with the brand.
Doyle Bramhall II — photographed with one, and described in Equipboard’s entry as using it as his main drive. Given Bramhall’s whole aesthetic sits in the blackface-Fender-through-a-slightly-broken-up-amp space, this is about as on-brief a user as the pedal could ask for.
Yvette Young (Covet) — visible on the board she photographed for her album sessions. Worth noting because the Jan Ray gets typed as a blues-and-session pedal and Young’s math-rock tapping vocabulary is about as far from that as you can get while still plugging into an amp.
Richard Fortus (Guns N’ Roses) — confirmed via a post from Vemuram’s own official Instagram account thanking him for his support. That is brand-sourced rather than independent, so treat it as one notch below a Rig Rundown, but a manufacturer naming a specific current player of a major touring act is a claim they would be publicly embarrassed to get wrong.
Kanami Tono (Band-Maid) — shared an updated pedalboard on her official Instagram in August 2023 with the pedal on it.
Isaac Wood (Black Country, New Road) — visible on his board in a dated photograph.
Joey Landreth (The Bros. Landreth) — the Jan Ray is on the left of his board in video footage.
Paul Davids — visible in one of his own Instagram posts. Not a touring name, but a guitarist whose YouTube reach has probably sold more of these pedals than any endorsement.
One pattern worth naming: the density of Japanese and Korean players in the Jan Ray’s documented user base is striking and almost never mentioned in Western coverage. The pedal’s reputation in East Asia was built independently of, and in some markets ahead of, its reputation in the US and Europe.
Documented by the player’s own words
Toru Kitajima (TK, Ling Tosite Sigure) gave the clearest first-person account we found. Talking through his rig, he lists his time-based effects and then says plainly that in the distortion department he uses the Vemuram Jan Ray and a Barbarossa Uranus. He runs it as a booster for his clean sound, in a role previously filled by a different pedal. That is a specific, functional description from the player himself, which is worth more than ten board photographs.
Brand-sourced, and flagged as such
Scott Henderson is quoted praising the Jan Ray as the best boost pedal he has heard for blues. The quote appears on Vemuram’s own artist pages. Henderson is a real Vemuram artist and there is no reason to doubt the relationship, but a testimonial hosted by the manufacturer is a testimonial, and we would rather label it than launder it.
Claims we could not stand behind
Mike Stern appears on the Jan Ray’s aggregator page, but the “source” field attached to his entry contains nothing but spam — several hundred words of unrelated advertising copy that has nothing to do with guitars, pedals or Mike Stern. Whatever evidence originally sat there has been overwritten. We are not going to claim Stern uses a Jan Ray on the strength of a vandalised database field, and neither should anyone else.
The same page also lists the Jan Ray as appearing on Kirk Fletcher’s album My Turn, dated 2010. That date sits at or before the earliest point the pedal is documented as existing, which makes it an anachronism rather than a fact. Fletcher may well have used one later; the album credit as stated does not hold up.
The general lesson, and it applies to every boutique pedal with a long roster: a crowd-edited gear database is a starting point for research, not a citation. Its individual entries range from a timestamped Rig Rundown screenshot to a field somebody filled with spam three years ago, and the page presents both with identical formatting.
Six settings that work
Clock positions, with Saturation at the factory centre unless noted. As always these are starting points for a real amp in a real room, not destinations.
1. The always-on (blackface lift)
Volume 10 o’clock, Gain 8 o’clock, Bass 11 o’clock, Treble 12 o’clock. This is the setting the majority of professional users are actually running. It is not an effect; it is a slightly better version of your amp. Turn it off mid-song and the amp sounds like something has been taken away.
2. Edge of breakup, Stratocaster into a clean amp
Volume 11, Gain 11, Bass 10, Treble 11. Roll the guitar volume back to 7 and it cleans up almost completely; dig in and it snarls. The Bass at 10 keeps the low strings from blooming, which is the difference between “vintage Fender” and “mush.”
3. Humbuckers, tightened
Volume 10, Gain 10, Bass 9, Treble 1 o’clock, Saturation slightly counter-clockwise of centre. Humbuckers are exactly the case where the trimmer earns its keep — pulling saturation back stops the low mids congealing and lets the treble control do useful work.
4. Slide and heavy strings
Volume 11, Gain 1 o’clock, Bass 12, Treble 10. More weight, more sustain, less top. This is broadly the territory Joey Landreth’s open-tuned baritone-ish approach lives in, and the Jan Ray’s sustain without obvious compression is genuinely useful here.
5. Stacked in front of a Tube Screamer
Jan Ray first: Volume 1 o’clock, Gain 9, Bass 11, Treble 11 — then into a TS9 with its own drive low. The Jan Ray provides level and clarity, the Screamer provides the midrange hump. Reverse the order and you get a muddier, more compressed result, which some players prefer for leads.
A caveat that comes up repeatedly in owner reports: the Jan Ray can dominate a signal chain. Its output is high enough and its voice strong enough that stacking it with other drives is fiddlier than stacking, say, a Nobels ODR-1. If your board is built around layered gain stages, audition it with the whole chain, not on its own.
6. Clean boost for a solo
Volume 2 o’clock, Gain fully counter-clockwise, Bass 12, Treble 12. At minimum Gain the pedal is closer to a level-and-EQ device than an overdrive, in the same functional slot as an Xotic EP Booster but with actual tone controls.
How it compares
Versus the Timmy and the MXR Timmy
Covered above, but the practical summary: the MXR Custom Shop Timmy is $145, is an official Cochrane collaboration, uses an LF353 op-amp, and gets you the great majority of what this circuit does. The Jan Ray is brighter, has more available gain, is built to a considerably higher physical standard, and costs $388. If money is a consideration at all, start with the MXR. If you have played both and prefer the Jan Ray, you have not been fooled — the treble voicing really is different — but you should know exactly what the premium is buying.
Versus the Klon family
Different animals. A Klon Centaur or a Wampler Tumnus works by blending a clean path with a driven one, which produces its characteristic firmness in the lows and a midrange push that the Jan Ray simply does not have. Reviewers who have compared them are consistent on this: the Jan Ray is not a mid-voiced pedal and will not replace a Klon-style drive on a board that needs one. They stack together perfectly well.
Versus the Tube Screamer family
Almost opposites. A TS808 scoops the lows, humps the mids and compresses; the Jan Ray keeps the lows, leaves the mids flat and compresses very little. If your complaint about Tube Screamers is that they make every guitar sound like the same guitar, the Jan Ray is the structural answer to that complaint. If you like what a Screamer does to a Les Paul into a Marshall, the Jan Ray will sound thin and unhelpful to you. Both reactions are common and both are correct.
Versus the King of Tone and Prince of Tone
The Analog Man King of Tone and its single-channel sibling the Prince of Tone descend from the Marshall Bluesbreaker rather than the Timmy, and they are softer, rounder and less bright than the Jan Ray. At least one review has argued the Jan Ray rivals the King of Tone directly at similar money. The relevant practical difference is availability: the King of Tone has a years-long waiting list, and the Jan Ray is a pedal you can order this afternoon. For a lot of buyers that has been the entire decision.
Versus the wider transparent field
The JHS Morning Glory V4 is another Bluesbreaker descendant and is brighter and more polite. The Fulltone OCD is louder, more aggressive and considerably less transparent. The Boss BD-2 gets to a similar edge-of-breakup place for a tenth of the price with more fizz and less refinement. The Nobels ODR-1 BC is the other great session-player secret weapon and has the opposite EQ philosophy — a broad mid scoop with a Spectrum control — but occupies the same “put it on and leave it there” role. And if you want to audition nine Screamer variants before deciding you did not want a Screamer at all, the JHS Bonsai is an efficient way to find out. A two-drive board of a Keeley D&M Drive covers similar ground for less.
Buying guide, September 2026
What it costs
New street price sits at $379–$388, with $388 being the figure at the largest European retailer selling into the US market. That has been remarkably stable — this is not a pedal that discounts. Used examples on the major marketplaces typically run £280–£300 / $300–$350, which is a smaller discount off new than most boutique pedals see, because demand has not softened.
For context within Vemuram’s own range at the same retailer: Shanks ODS-1 $435, Butter Machine $457, Las Lunas $455, Spiritone $487. The Jan Ray is the cheapest thing the company makes, which tells you something about where the brand positions itself.
Which version
The standard Jan Ray is the one to buy. There are two categories of variant worth knowing about:
Signature editions. The Jan Ray for MA — Mateus Asato — was a limited run of 500 units in a clear-coated “Pink Gold” finish, with more total gain and slightly more compression than the standard pedal while keeping headroom. A Tomo Fujita version also exists. These trade well above standard prices and are collector items; the tonal differences are real but modest, and you are mostly paying for the run size.
The Ibanez collaboration. Vemuram and Ibanez jointly produced the TSV808, a Vemuram reinterpretation of the TS808 in the classic Screamer enclosure. It is discontinued and now trades at several times its original price. It is a genuinely interesting object but it is a Tube Screamer, not a Jan Ray, and buying one expecting the Jan Ray voice will disappoint you.
What to check when buying used
Brass hides very little, so a visual inspection tells you most of what you need. Look at the jacks for thread damage, check the footswitch feels positive rather than mushy, and — importantly — open the pedal and look at the Saturation trimmer. A previous owner may have left it at an extreme, and a Jan Ray with the trimmer buried at either end will sound wrong in a way that has nothing to do with the pedal being faulty. If the seller cannot tell you where it is set, factor a fifteen-minute setup session into your plans and do not judge the pedal in the first five minutes.
Who should not buy this pedal
Three groups, stated honestly. First, anyone who already owns and loves a blackface Fender amp — at least one reviewer concluded that owning the real thing measurably reduces the pedal’s appeal, and that is a fair observation. Second, anyone who wants a mid-forward drive; the Jan Ray does not do that and no amount of knob-turning will make it. Third, anyone who will be bothered every time they look at it by the circuit’s provenance. That last one is not a joke — a pedal you feel faintly guilty about is a pedal that comes off the board within a year.
Ownership notes
Power
Regulated 9 V DC, centre negative, 5.5 x 2.1 mm — the universal standard. Current draw of 5 mA means it will run happily off any isolated supply outlet with room to spare, and off a daisy chain if you must. Battery operation via a standard 9-volt is supported and the low draw means a battery lasts a long time, but with 428 grams of brass to unscrew every time, most owners power it externally and never look inside again.
Vemuram specifies 9 V. Unlike some boutique drives, there is no published 18 V option — do not assume the higher voltage will give you extra headroom, because the manufacturer has not said it is safe.
Bypass and placement
True bypass, per Vemuram’s published specification and every retailer listing. Practically this means the Jan Ray adds no buffering to your chain, so if it sits early in a long cable run on a big board, you will want a buffer somewhere — a tuner with a good buffer at the front is the usual answer.
Placement: early in the chain, before modulation and time-based effects, in the same slot you would put any other drive. If you are stacking, the Jan Ray’s high output means it usually wants to be first, feeding the pedal that provides the character, rather than the other way round.
Living with brass
The enclosure will develop a patina. Some owners polish it, most do not. It does not affect anything, and a decade-old Jan Ray with a mottled finish is a better-looking object than a new one. The weight is a genuine consideration for a flight-cased board — four Vemuram pedals is well over a kilogram and a half of enclosure before you count the electronics.
Frequently asked questions
Is the Vemuram Jan Ray just a Timmy?
Circuit analysis published by independent DIY builders concludes it is the Timmy topology with a different op-amp (LM4558 rather than JRC4559) and a lower treble rolloff frequency (around 2.8 kHz rather than 10.6 kHz), in a brass enclosure. Those changes are audible — the Jan Ray is brighter with more available gain — but they are changes to a shared design rather than a different design. Vemuram’s marketing describes the pedal as an original recreation of a blackface Fender amp and does not mention Paul Cochrane. That combination is the source of the long-running controversy.
Does it actually sound like a blackface Fender?
It sounds like a good clean amp getting louder and firmer without getting thicker, which is the useful part of the blackface reference. It will not turn a modelling amp into a 1965 Deluxe Reverb, and it is not a preamp or an amp-in-a-box. If your amp is already broadly Fender-voiced, the Jan Ray flatters it considerably; if your amp is a British-voiced crunch machine, the effect is less obviously idiomatic.
What is the internal trimmer for and should I touch it?
It adjusts the pedal’s overall saturation, letting you match it to your pickups. Yes, you should touch it once — deliberately, with your own rig, in a dedicated session — and then leave it. Fully clockwise is woolly and fully counter-clockwise is thin; the useful range is the middle. You need a small flat-head or jeweller’s screwdriver and you have to open the enclosure.
Is the Jan Ray true bypass?
Yes, per Vemuram’s published specification and consistently across retailer listings. Note that this means it contributes no buffering, so a board built entirely from true-bypass pedals with long cable runs will still want a buffer somewhere.
Can I run it at 18 volts?
Vemuram specifies a regulated 9 V supply or a 9 V battery and publishes no 18 V rating. Absent a manufacturer statement, do not do it. The pedal already has more output than most players need, so the usual reason for running a drive at 18 V — headroom — is not pressing here.
Why is it so heavy?
The enclosure is machined solid brass, which Vemuram chose for its shielding properties and which gives every pedal in the range its distinctive gold appearance. At 428 grams it is roughly three times the weight of a comparable aluminium pedal. Brass is a real electromagnetic screen; claims that the enclosure material audibly alters the sound of the circuit inside are not supported by anything measurable.
Is it worth $388?
It is worth it if you have played the $145 MXR Custom Shop Timmy, preferred the Jan Ray, and can afford the difference — the voicing genuinely is different and the build quality genuinely is exceptional. It is not worth it if you are buying on reputation without comparing, because the closest legitimate alternative costs a third as much and pays the person who designed the circuit. That is an unusually clear-cut recommendation for a boutique pedal and we are making it deliberately.
Which famous players actually use one?
Independently documented by photo, video or the player’s own words: Mateus Asato, Michael Landau, Doyle Bramhall II, Yvette Young, Toru Kitajima of Ling Tosite Sigure, Kanami Tono of Band-Maid, Isaac Wood of Black Country New Road, Joey Landreth, Paul Davids and Richard Fortus of Guns N’ Roses. Scott Henderson’s endorsement is real but hosted on Vemuram’s own site. A widely-repeated Mike Stern attribution rests on a database entry whose source field has been overwritten with spam, and we do not consider it established.
What is the difference between the standard Jan Ray and the Mateus Asato version?
The Jan Ray for MA was a 500-unit limited run in a “Pink Gold” clear-coated brass finish, voiced under Asato’s supervision with more total gain and a little more compression while retaining headroom. Everything else — controls, power, dimensions, weight — matches the standard pedal. It trades well above standard prices, mostly on scarcity rather than tone.
Where can I buy one, and does Vemuram sell direct?
Through authorised dealers worldwide; Vemuram maintains a dealer list by region and also operates a Japanese web shop. Note that vemuram.com is heavily JavaScript-driven, so if you are researching from a text browser, an archive, or an AI assistant, most of the site’s content will appear blank — go to a dealer listing or the brand’s Instagram for current product information.
