Most overdrive pedals arrive shouting. They have a story about a rare amplifier, a dead circuit designer, a serial number nobody can verify, and a name in Latin. The Blue Note has none of that. It is a small blue box with four knobs, it does one narrow thing, and for most of its life it has been the pedal that gear forums forget to mention.
And yet: for well over a decade it has been sitting in the middle of John Scofield‘s signal chain — one of maybe five living guitarists whose tone is genuinely, immediately identifiable within two notes — between a modified Boss EQ and a wah. It has turned up on Snarky Puppy boards. It has been photographed on Nashville session rigs and on indie pedalboards in Seoul. Guitar World’s Trevor Curwen gave the newest version four and a half stars in April 2025 and complained about exactly one thing: the price.
This is the story of a pedal that never had a marketing hook, went through three generations while nobody was looking, briefly lost the feature that made it interesting, and then got it back nine years later. It is a guide, not a review — what the Blue Note is, which version you actually want, who is verifiably using it, and how to make it sound like the thing it is good at.
The short version
The Blue Note is a low-to-medium-gain overdrive with a four-knob layout — Volume, Gain, Tone and Fat — built around a voicing that J. Rockett Audio Designs themselves describe as “woodsy,” with more available gain than a standard Tube Screamer but far less midrange hump. Where a TS808 narrows and pushes, the Blue Note widens and warms.
There have been three of them. The original Blue Note Pro Series, a larger enclosure with a “Hot” switch that adds gain, volume and thick low-mids. The Blue Note Tour Series, launched 2 November 2016 at $189, a compact version that was sonically identical but dropped the Hot switch entirely. And the current Blue Note Select, a full V2 redesign at $229.99 that brings the Hot switch back, adds custom knobs and a custom-mixed electric blue finish, and — by the company’s own account — improves the low end both in and out of Hot mode.
The fourth knob is the one that matters. Fat is a low-end trim, and it is the reason this pedal works on a Telecaster into a blackface Fender and on a humbucker into a Marshall without either combination sounding wrong. It is the single control that most transparent drives don’t give you.
J. Rockett’s own advice on how to use it is unusually honest for a product page, and worth quoting because it is correct: get your amp “just past the minimum edge of breakup,” then add the pedal. The Blue Note is not designed to manufacture distortion from a sterile clean amp. It is designed to push something that is already leaning.
Three pedals, one name: sorting out the family
This is where most buyers get lost, and the confusion is not entirely their fault — J. Rockett’s own website still carries a page title reading “Tour Series Blue Note Overdrive” on the URL that sells the Select. If you have been comparing listings and found four knobs on one, a switch on another and wildly different prices, here is the actual sequence.
Blue Note Pro Series — the original
The Pro Series came first and set the voicing: transparent, organic, warm, with a Hot switch that flips the pedal from a flat EQ into bumped-up mids for lead work. It is the largest of the three at roughly 3 inches wide by 4.75 inches deep, with the standard J. Rockett Pro Series appointments — true bypass, 9V DC or battery, durable metal housing, made in the USA.
Every single verified artist sighting we found — and there are eight of them, covered in detail below — attaches to this version, not to the compact reissues. That is a function of timing more than merit. The Pro Series had a four-year head start and it landed in the hands of players who were building serious boards in the early 2010s.
Blue Note Tour Series — the compact one, with a catch
On 2 November 2016, J. Rockett announced the Blue Note as the seventh release in its Tour Series — the line the company described as “designed with the influence of a host of top Nashville and LA touring artists to address their needs on the road.” The same programme produced The Dude and the Archer Ikon.
The press release was blunt about what it was: “a small, compact version of the current production Pro Series Blue Note… identical in sound to the original Blue Note, but does not offer the ‘Hot Switch’ option.” Rugged steel enclosure, the then-new Speed Switch system, jacks at the head of the pedal, 9V DC operation, $189 street.
A specification note worth flagging. That press release lists the Tour Series Blue Note as “approximately 2.65″ x 2.65″ in size,” which is not the enclosure J. Rockett actually used. Every Tour Series pedal, including this one, sits in the same footprint as The Dude and the Archer Ikon — roughly 102 x 59 x 32 mm, or about 4 inches by 2.3 inches. Third-party listings carry the correct figure. If you are planning board space from the press release number, you will be a full inch short. (Equipboard’s product record also lists the Tour Series as “available since April 2016,” which conflicts with the November press release; treat the press release date as authoritative.)
The Hot switch omission was the interesting decision, and it did not go unnoticed. In guitar.com’s group review of four Tour Series pedals, the verdict on the Blue Note was politely lukewarm: a straightforward clean tone with sweet breakup, ideal for players chasing transparency, but “the absence of a mid-pushing switch may leave some wanting more versatility.” It shone as a mild crunch channel, the reviewer wrote, without quite delivering the character some hoped for.
File that away. It is the hinge of the whole story.
Blue Note Select — V2, and the Hot switch returns
The Select is the current production model, and J. Rockett’s own description of it is refreshingly free of mythology: “The Blue Note Select is a ‘V2’ of our favorite circuit. The original Blue Note Pro Series was the first and that included the ‘Hot’ switch. We then introduced the Tour Series that did not have the ‘Hot’ switch. The newest Blue Note Select not only includes the ‘hot’ switch but also includes major improvements to the looks, the sound and the overall feel.”
The improvements they name are specific: custom-made knobs, a custom-mixed electric blue, and — “by far the biggest improvement” — the low end, both in and out of Hot mode. The company calls it possibly their best overall low-gain drive.
Trevor Curwen reviewed it for Guitarist, published on Guitar World on 20 April 2025, and awarded four and a half stars. His summary of the format: “Prior to this, there was the larger but similarly equipped Blue Note Pro, and then a smaller Tour Series version without the Hot switch. Now, that Hot switch has been reinstated in another nicely compact offering that’s had a complete makeover.”
Which is to say: nine years after the compact version launched without the mid-push, and after a review cycle that specifically identified its absence as the limitation, J. Rockett put it back and shrank the enclosure anyway. That is not a common arc in boutique pedals, where the usual move is to release a fourth variant and let the customer sort it out.
What the four knobs actually do
Volume sets output level, and there is meaningful headroom above unity. Curwen notes that with the Gain knob down there is “a little bit of clean boost available beyond unity on the volume knob” — enough to use the Blue Note as a straight level push into an amp front end, in the same job you might otherwise give an MXR Micro Amp or a Keeley Katana.
Gain controls the amount of clipping, and it is genuinely useful across its full sweep rather than only in the top third. At minimum you are at boost. Around nine o’clock you get the “hair” that is this pedal’s central trick — a texture rather than an effect. Past noon it becomes a proper overdrive with more available gain than a Tube Screamer, which surprises people who file it under “transparent boost.”
Tone adjusts highs and, in J. Rockett’s own phrasing, “smoothness.” It works on the crucial top-end frequencies rather than acting as a global filter, so unlike some drives you can move it a long way without the pedal falling apart at either extreme.
Fat is the one to understand. J. Rockett describe it as a subtle low-end trim; Curwen describes it as pushing the lower midrange and adding “a lot of body.” Both are right, because in a low-gain circuit those are the same adjustment heard from two directions. Owners on forums have converged on the same reading — the Fat parameter adjusts low-end trim to suit different musical styles, and it is the control that lets a single pedal serve a Strat and a 335 without recompromising.
The Hot switch (Pro and Select only) adds gain, adds volume, and adds thick low-mids. Curwen’s read on the Select’s implementation: “a touch of extra gain and a perceived slight increase in presence, taking things a stage further into more medium-gain, raunchy territory.” It is not a channel switch and it is not a solo boost. It is a second, slightly angrier voice for the same pedal.
Specifications
Famous players: what actually holds up
We check these individually rather than trusting brand rosters, because brand rosters in this corner of the market are frequently recycled. The Blue Note’s list turns out to be unusually well-documented, and unusually jazz-heavy.
John Scofield — the one that matters
John Scofield is the headline, and the documentation is about as good as it gets.
His pedalboard was built by Mason Marangella of Vertex Effects, and Vertex published the full spec sheet. The signal path runs: input buffer, into a true-bypass loop holding a DigiTech Whammy XP100, into a TC Electronic Polytune Mini, into a Vertex Axis Wah, into the Rockett Blue Note, into a Vertex-modified Boss GE-7, then out through a break-out insert to a modified Boss CE-3 chorus, a Neunaber mono WET reverb, a loop for a Boomerang phrase sampler, and finally a buffer/splitter feeding two amplifiers. The GE-7 is modified for transparency and upper-midrange emphasis so it functions as a treble booster; the CE-3 is modified for faster speeds and more warble to get closer to a Leslie.
The Blue Note sits directly before that EQ. It is the only conventional drive pedal on the board.
Scofield has explained the choice on camera, and the reasoning is characteristically unglamorous: Marangella convinced him to use it because it is true bypass. He then described what it does for him — “This is pretty subtle. It’s a distortion thing, but it’s a blues kind… not a real crunch. As much as anything I use the distortion of the AC30. It’s a natural thing.”
Two things are worth pulling out of that. First, this is an endorsement of the pedal’s restraint, not its gain. Second, Scofield is explicitly saying the amp is doing most of the work — which is exactly the usage J. Rockett recommend on their own product page. The player and the builder independently arrived at the same instruction.
Honest caveat: Vertex dated that board specification to December 2012, four years before the Tour Series existed. Scofield’s Blue Note is a Pro Series. Anyone buying a compact Select to chase this sound is buying a descendant of the right circuit, not the identical pedal — although since J. Rockett describe the Tour Series as sonically identical to the Pro and the Select as a refinement of the same circuit with the Hot switch restored, the gap is narrower than it usually is with reissues.
Mark Lettieri and Chris McQueen — two-thirds of a Snarky Puppy guitar section
Mark Lettieri, of Snarky Puppy and The Fearless Flyers, has posted photographs of his pedalboard with a Blue Note on it. Chris McQueen, also of Snarky Puppy, has a Blue Note visible in photographs from the Sylva recording sessions. Both are photo-verified rather than quote-verified, which is a lower tier of evidence than the Scofield material but still a great deal better than a name on a brand page.
Lettieri is a recurring presence in this corner of the pedal market — he also turns up as a documented user of The Dude, which suggests a working relationship with the brand’s voicing rather than a one-off.
Kenny Greenberg — the Nashville verdict
Kenny Greenberg is one of the most-recorded session guitarists in Nashville, which makes him a more useful witness than most touring players: session guys audition dozens of drives a year and keep almost none. His description of the Blue Note is the most precise summary of the pedal anyone has offered:
“It’s really transparent. It’s really more of a boost. There’s a little bit distortion to it that retains the character and the tone of the guitar, especially if you’re playing the Strat. You turn this on, and it just gets kind of a warm-sounding.”
“More of a boost” from a player at that level is a specification, not a criticism. It tells you where the pedal lives.
Grant Geissman — and a very informative shopping list
Grant Geissman, best known for his work with Chuck Mangione, told Vintage Guitar magazine about his rig in terms that place the Blue Note precisely: “I’m using a Yamaha G100. It’s a 1×12 and it’s super loud and very clean, which I need when I play jazz. I also use an old Boss OD-1 that’s very smooth-sounding. I recently got a Zendrive, which is very cool, and a J. Rocket Blue Note.”
An OD-1, a Zendrive and a Blue Note is a coherent set. All three are low-gain, all three are about texture rather than saturation, and all three are chosen by a player whose amp is deliberately clean and loud. That is the Blue Note’s natural habitat described by accident.
The rest of the documented roster
Jeremy Freedman of The Neighbourhood has a Blue Note visible on his board in video footage. Charles Bissell of The Wrens posted a photograph of his board set up for a solo show with the pedal on it. Australian guitarist Adam Miller has one documented in a pedalboard photograph. And on the Tour Series specifically, Daniel Kim of the Korean band wave to earth has been using one since 2024 — his own account describes it as capable of being either subtle or angry, and it has stayed on the wave to earth board through to the present.
Daniel Kim is, as far as we can establish, the only artist sighting attached to the Tour Series rather than the Pro. That gap says less about the pedal than about who was building boards when.
What the roster tells you
Sort those players by genre and the pattern is stark. Equipboard’s genre breakdown for the Blue Note runs Rock first, then Jazz, Funk/Soul, Jazz Fusion, Contemporary Jazz — with Blues, notably, further down the list than the pedal’s own name implies.
That is unusual. Most overdrive pedals show up as rock-and-blues instruments with a scattering of outliers. The Blue Note is genuinely a jazz and fusion pedal that happens to be marketed at blues players, and the reason is the same in every case: it does not compress much, it does not scoop, it does not add a midrange signature you would have to play around. For a player whose harmonic language is complicated, a drive that leaves chord voicings legible is worth more than one that sounds exciting on a power chord.
If you play a lot of extended chords and you have been frustrated that every overdrive turns your voicings to porridge, this is the section of the article that was written for you.
Tone recipes
The Scofield: transparent hair on a cooking amp
Gain 8 o’clock, Volume 1 o’clock, Tone noon, Fat 10 o’clock, Hot off. Amp: a Vox-style circuit already breaking up, or a blackface Fender pushed to the edge. This is the “not a real crunch” setting — the pedal adds texture and a small level lift while the amp supplies the actual distortion. Put a transparent, upper-mid-focused EQ after it if you want the treble-boost function Scofield gets from his modified GE-7.
The Nashville boost: Strat into clean, warmed up
Gain fully counter-clockwise, Volume 2 o’clock, Tone 11 o’clock, Fat noon, Hot off. Greenberg’s setting in all but name. Almost no clipping, meaningful level, and Fat filling in the low mids that a single-coil bridge pickup gives away. Leave it on all night.
The jazz-box setting: legible chords, gentle grind
Gain 10 o’clock, Volume noon, Tone 10 o’clock, Fat 9 o’clock, Hot off. Fat pulled back because an archtop already has body and adding more turns it woolly; Tone backed off to keep the top from getting glassy. This is the setting that keeps a 13th chord readable, which is the whole reason jazz players end up here.
Hot mode leads (Pro and Select only)
Gain 1 o’clock, Volume noon, Tone 1 o’clock, Fat 1 o’clock, Hot engaged. Medium gain, mids forward, extra perceived presence. This is the closest the Blue Note gets to a conventional lead sound and it is still considerably more restrained than a Fulltone OCD at similar settings. On the Select, the improved low end is most obvious here.
Pushing a Plexi
Gain 11 o’clock, Volume 1 o’clock, Tone noon, Fat 2 o’clock, Hot engaged. J. Rockett specifically cite using the Select to push a Marshall Plexi “because you can really tweak your bottom end to match.” Curwen tested the Select on a vintage JMP50 and reported the same result. Fat is doing the heavy lifting — a Plexi’s low end needs feeding, not trimming.
As a stacking partner
Gain 9 o’clock, Volume noon, Tone noon, Fat 11 o’clock, first in the chain. Owners have observed that the Blue Note “acts as a sort of compressor when stacked with other gain pedals, enhancing the overall tonal blend without overwhelming the signal.” Put it before a mid-heavy drive to add body underneath, or after one to smooth the top. It is a good citizen either way, which is not true of every low-gain pedal.
All settings assume clock positions and an amp already at or just past the edge of breakup, which is the manufacturer’s own recommended starting point and, not coincidentally, how every documented user above runs it.
How it compares
The Blue Note occupies a crowded shelf. Here is where it actually sits relative to the pedals it gets cross-shopped against.
Versus a Tube Screamer. The TS9, TS808 and Maxon OD808 all narrow the bandwidth and push the mids. That is a feature when you are trying to cut through a band; it is a liability when you want your guitar to still sound like your guitar. J. Rockett’s marketing line — more gain than a typical Tube Screamer, with a woodsy character — is accurate on both counts. If you have tried a TS and found it nasal, the Blue Note is the corrective.
Versus a Klon-type. The Klon Centaur and its descendants — including J. Rockett’s own Archer Ikon, the Wampler Tumnus and the EHX Soul Food — work by blending clean signal with clipped signal and adding a treble lift. They are boost-forward and slightly hi-fi. The Blue Note is warmer, darker and more amp-like, with the Fat control giving you low-end authority a Klon-type simply does not offer. Within the J. Rockett catalogue the two are complementary rather than competing, which is presumably why both survived the Tour Series cull.
Versus a D-style drive. The Dude, the Vemuram Jan Ray and the Zendrive are all chasing amplifier feel through blended clipping and a strong midrange character. The Blue Note is less characterful and more neutral. Notably, Grant Geissman owns both a Zendrive and a Blue Note — they are not redundant.
Versus the transparent school. The Nobels ODR-1, MXR Timmy, Greer Lightspeed and Analog Man King of Tone are the direct competition, and honestly the choice between them comes down to EQ philosophy. The ODR-1 has its Spectrum control; the Timmy has independent bass and treble cuts; the King of Tone has a three-way voicing switch per channel. The Blue Note gives you one Fat knob and one Hot switch, which is less flexible and considerably faster to dial. Forum owners have specifically praised it for avoiding the tone compression and harshness some experience with certain other transparent drives.
Versus the Boss options. A BD-2 Blues Driver costs a fraction as much and covers adjacent ground with more sparkle and more grit; the OD-3 is smoother. Neither is as transparent, and neither has the Fat control. Whether $230 of difference buys you enough is a question only your ears and your budget can settle, and it is the one criticism Guitar World levelled at the Select: “We’d like it even more if it cost less.”
Which version should you buy?
Buy the Select if you are buying new and you want the Hot switch, the improved low end and the current warranty. It is the most complete version of the pedal and the only one still in production. At $229.99 it is expensive for a low-gain drive and nobody, including its reviewers, pretends otherwise.
Buy the Tour Series used if you want the core voicing at the lowest cost and you know for certain you will never reach for a mid-push. It is sonically the same pedal minus one switch. Used prices are typically well under the Select’s, and the pedal is built to survive touring. Be aware that the missing Hot switch was the specific thing critics flagged, and it is not a feature you can add later.
Buy the Pro Series used if you want the version every documented artist is actually using and you have board space for a 3 x 4.75-inch enclosure. Same feature set as the Select, older circuit revision, larger footprint. If your goal is specifically the Scofield chain, this is the one on his board.
Do not buy any of them if your amp is small, clean and stays clean. The Blue Note’s entire design philosophy assumes an amp that is already at the edge. Into a pristine clean platform it will sound thin and slightly pointless, and you would be better served by something like a Wampler Plexi-Drive Deluxe or a full amp-in-a-box that supplies its own character.
Living with one
Power and board integration. 8 mA on the Select is nothing — any isolated supply will run it, and it will not care which output it sits on. Standard centre-negative 9V, 5.5 x 2.1 mm. Battery operation is supported on all three versions if you want it, which on a true-bypass pedal with no buffer is genuinely viable for a rehearsal.
Placement. Early in the chain, after wah and pitch and before EQ and modulation, is where every documented user puts it. Scofield’s board follows exactly that order. If you run multiple drives, the Blue Note works well as the first one — it adds body that later stages can build on.
Build. Owners consistently describe J. Rockett enclosures as solid and reliable, and there is no meaningful pattern of failure reports. Top-mounted jacks on the Tour Series and Select save real estate; the Pro Series’ side jacks do not.
Bypass. True bypass on all three. This is not a footnote — it is literally why John Scofield’s tech put one on his board. If you run long cable runs and a mostly-passive chain, add a buffer somewhere else.
The one real complaint. Price. Owners who have paid it generally defend it, describing the pedal as an outstanding investment for its clarity, but the phrase “expensive for a low-gain pedal” recurs often enough in owner discussions that it should be treated as the consensus reservation rather than an outlier grumble.
Frequently asked questions
What is the difference between the Blue Note Pro, Tour Series and Select?
The Pro Series is the original, in a larger enclosure, with a Hot switch. The Tour Series (2016) is a compact version, sonically identical, without the Hot switch. The Select is the current V2 — compact, with the Hot switch restored, custom knobs, an electric blue finish and improved low-end response in both modes. All three share the same Volume/Gain/Tone/Fat layout and the same fundamental voicing.
What does the Fat knob do?
It trims and shapes the low end and lower midrange. J. Rockett describe it as a subtle low-end trim; reviewers describe it as adding body and pushing lower mids. Practically, turn it up to thicken a single-coil or feed a Marshall’s bottom end, and turn it down to keep an archtop or humbucker from getting woolly.
Is the Blue Note a Tube Screamer clone?
No. It has more available gain than a typical Tube Screamer and a substantially different EQ character — wide and warm rather than mid-humped and narrow. If you want a TS, buy a TS9. The Blue Note is what you buy when the TS voicing is the problem.
Does John Scofield really use one?
Yes, and it is well documented. Vertex Effects, who built his pedalboard, published the full signal chain with the Rockett Blue Note in it, and Scofield has explained on camera that his tech recommended it for being true bypass. His is a Pro Series — the board specification predates the compact versions.
Is it good for jazz?
Better than most. The genre data on documented users skews heavily toward jazz, fusion and contemporary jazz, and the reason is that the pedal does not compress or scoop enough to blur complex chord voicings. It is a jazz-friendly overdrive that happens to have a blues name.
Does the Blue Note need a driven amp?
It strongly prefers one. J. Rockett’s own guidance is to get the amp just past the minimum edge of breakup and then let the pedal take it further, and every verified user runs it that way. Into a fully clean, high-headroom amp it can sound like a clean note sitting underneath a thin overdrive — a limitation the manufacturer explicitly acknowledges about low-gain pedals generally.
Does it stack well?
Yes. Owners report it behaves almost like a light compressor when stacked, blending rather than fighting. Run it first in a multi-drive chain to lay down body, or after a mid-forward drive to smooth the top end.
Why is the Select more expensive than the Tour Series was?
Nine years of inflation, a full circuit redesign, custom-tooled knobs and a custom-mixed finish, plus the reinstated Hot switch. Whether that adds up to the difference is a judgement call. Guitar World’s only stated criticism of an otherwise four-and-a-half-star pedal was the price.
