Time to Start Building Pedals? Here’s the Ultimate DIY Kit Roundup
Want to try your hand at stompbox assembly but don’t know where to start? We fired up our soldering irons to bring you a deep dive on making pedal kits.
Building your own pedal can feel unattainable—like something only geniuses and magicians can do. Or at least people who took an electronics course. Many of us are content to leave it that way. Those things on our boards sound cool when you click ’em, and that’s all we need to know. But some of us want to get our hands dirty and figure out what ticks behind the click. If you’re in the latter camp, this one’s for you.
There are a wealth of pedal-kit options today, from long-standing DIY-focused companies to established pedal builders who want to get in on the fun. But, really, how hard is building a pedal? Can any of us just, like, do it? And where are the best places to start?
Well, we’re here to tell you that, yes, any of us can. Both of us have limited experience—Jason is brand new, and Nick started building kits last year (you can watch his inauspicious beginnings over on our YouTube channel). But with nothing but some baseline soldering skills and a sense of adventure, we set out to survey the pedal-kit market by doing. What we’ve assembled are six kits from JHS, Third Man, StewMac, Aion FX, General Guitar Gadgets, and Pedal Parts and Kits that range from the simplest no-solder option to step-by-step builds to kits that’ll have you testing components and following wiring diagrams to complete the task. We’ve rated each kit: “tone” for the overall sound of the pedal, “design/build” for the experience of building the kit, and “value.”
If you build a few of these, you’ll probably end up with a better idea of what your pedals are doing, pick up some skills, and have some new pedals for much cheaper than you might otherwise. The next step is learning to mod and design your own circuits, and then you’ll be on your way to launching your own pedal company!
Pedal Parts and Kits sells all the parts and components you might need for pedal building, plus a variety of kits created in collaboration with GuitarPCB, which sells printed circuit boards (PCBs) and hosts a forum. I opted for their Pump’d Up Tone Bender, which is a MkII clone featuring vintage germanium PNP transistors. This design adds a charge pump to the power section, inverting the circuit to a modern negative ground, and allows the pedal to be daisy chained.
Right out of the box, I was impressed by the packaging of the Pump’d Up Tone Bender (PUTB). Each component group was separated into its own bag and clearly labeled. The resistors were separated by value, which made it easy to get started.
Tone Bender circuits are relatively simple, and this kit includes a handful of resistors and capacitors and a single IC. The germanium transistors include sockets, which makes installation easy, plus they allow for some transistor experimentation later if that’s your kind of thing. The kit includes a well-spaced 3PDT board for easy switch installation.
Documentation for the PUTB doesn’t include step-by-step instructions. Instead, Pedal Parts and Kits offers an online beginners build guide that will help any entry-level kit builder get started. I followed the included wiring diagram. It's clear and easy to follow, so I had no problem getting this together in a couple hours. The only time I went off script is with the pots, which can be mounted directly to the PCB, but I chose to wire them up instead.
The PUTB is a great-sounding Tone Bender MkII clone, with all the personality, versatility, and response you’d expect. There’s a world of usable, cutting tones across the range of the control set, and I could feel myself channeling Jimmy Page when I plugged my Tele and the PUTB into an old Fender Champ. At $85, if you’re up to the task, the PUTB is a fantastic way to get your hands on a MkII.—NM
Entering the General Guitar Gadgets realm can feel like wading into the deep end of the pedal-kit pool. Their site is loaded with a wide range of projects, and PCBs and kits are the company’s sole business. And if you’re at the point you’re ready to peruse schematics, the GGG site is a great resource because they make schematics available for each project.
Every GGG kit includes universal pedal-building instructions, project-specific instructions, a schematic, and a wiring diagram. Like the Pump’d Up Tone Bender build, this is for more experienced builders, not necessarily because it’s complicated but because the directions are more streamlined.
The D-Verb is based around the Belton Accutronics BTDR-2H, aka the “Belton Brick” reverb designed by Brian Neunaber. It’s a commonly used digital spring reverb module that can be found in plenty of pedals from small and large manufacturers. The pedal’s circuit consists of a handful of resistors, a few capacitors, one transistor, a pair of IC chips, and the reverb block.
The circuit board came together fast and the reverb block simply plugs into the PCB and gets a round of solder. The trickiest part of this kit is wiring up the footswitch, which doesn’t include a circuit board, so you have to get in there and connect everything yourself. It can be tricky to wire a switch for the first time, but it’s a good learning experience that’ll show you, at least a little bit, what’s going on in your switches.
The pedal sounds great—there’s a reason so many pedals use the Belton Brick. While most of those units include other controls or more advanced circuitry, the D-Verb is a simple, 1-knob effect that controls less or more. At subtle settings, it sounds suitably springy, while cranking the control adds some soft repeats with a nice level of drip. Overall, an easy build for a great no-frills reverb unit. —NMVintage-style fuzzes are the ultimate fodder for DIY pedal builders. Some of the best fuzz pedals consist of just a few components, so it’s easy to get your hands on a great circuit even when you’re just developing your skills. There are plenty of places to get started on your kit-building journey, but I’d argue that the Third Man Fuzz-a-Tron sets a new benchmark.
The Fuzz-a-Tron’s circuit is simple, consisting of just two transistors, four capacitors in two sizes, and four resistors that are all the same value, so there’s no testing components—just open the bag and get going. The confined space of small enclosures can be a real patience-tester, and tightly packed PCBs can make for some stressful soldering. The Fuzz-a-Tron alleviates those issues with a well-spaced PCB and an enclosure with plenty of space to maneuver. Once it’s all finished, builders can customize their wedge-shaped box with the included sticker sheet.
Third Man not only included detailed step-by-step instructions with the Fuzz-a-Tron, but made a build-along video that takes any guesswork out of the process and makes this the most well-documented kit I’ve seen.
The Fuzz-a-Tron sounds as retro as its shape suggests. Its volume and tone controls are interactive, and I prefer both fully cranked, where it sizzles like a Fuzzrite, but with a little less cutting treble and a tight midrange. Although there’s no LED on this pedal, which some will dislike, that is in line with plenty of vintage fuzzes. You’ll know whether it’s on or not, no matter the setting.
The Fuzz-a-Tron offers the best learning experience for beginning builders. That alone justifies your time. If the stickers feel a little gimmicky, don’t use ’em and decorate it on your own. Ultimately, the Fuzz-a-Tron’s vintage-voiced tone and great looks make it an essential stop on the kit-building journey. —NM
The Klon Centaur is arguably the most imitated circuit there is—even with DIY kits. A little over a decade ago, JHS made their own Klon clone, but it was discontinued after Klon’s Bill Finnegan started making the KTR. (On Reverb, these rare JHS models are going for close to $1,000.) Last November, JHS introduced the NOTAKLÖN, which is a complete pedal kit, but with a twist—no soldering skills needed. Admittedly, that puts the barrier to entry much lower than the other kits represented here, which makes this a solid first step for those looking for a foolproof initial build.
Building the NOTAKLÖN isn’t unlike building a very useful Lego project. The directions are mostly picture-based, all the parts fit together, and they include a few tools that you can punch out directly from the circuit board. Company founder Josh Scott even remembered to include a bit of GOOP to cover up those “magic” diodes.
I’ve tried quite a few Klon clones, and I have to say this JHS is up there with the very best. It gives you that real pronounced midrange, and paired with a slightly dirty amp, it can be set up for an incredible boost. The bonus feature is the switch on the front that works in Scott’s Shamrock mod, which adds more volume, mids, and an extra clipping gain stage.
Within about 20 minutes, I had gone from opening the box to kicking it on for the first time. The build feels incredibly solid. Combined with the extremely streamlined directions and the nearly unbeatable $99 price tag, the Notaklön delivers on nearly every front.—JSNot many guitarists are as closely connected to a singular tone as Robben Ford is to his Dumble Overdrive Special. Even though Dumble’s creations cover a wide range of tones, it’s Ford’s Dumble that set the benchmark. The original Hermida Zendrive was one of the first pedals that copped that D-style tone. Aion FX’s Azimuth is a DIY version that’s great for beginners since it doesn’t include a lot of parts, but teaches you plenty about basic pedal construction.
The kits from Aion are impeccably assembled. You get a bag of all the parts and components, a powder-coated enclosure, and a thoughtfully created build document. This was the very first pedal I ever built, so I needed to get my soldering skills together, but after that, assembly went very smoothly. In retrospect, I really like how Aion chooses ribbon connectors and enclosed input/output jacks for their builds. It keeps down, or limits, the amount of loose wires down and prevents any bad connections.
I previously owned a Lovepedal-era Zendrive and remembered how dynamic and smooth it sounded. Naturally, after playing the Azimuth, I was really regretting selling that pedal. With this circuit, the magic is really in the voice control, which helps tailor the low-end response. As you can hear in the clips, it sounds full and round, with plenty of punch. If the used prices for a Zendrive are a bit out of reach, then getting your hands on an Azimuth—even with the extra work—would be well worth it.—JS
Tremolo might be one of my favorite effects. Adding a bit of whirl to an arpeggio or doubling a lead line with something more aggressive that borders on a ring mod is always fun. StewMac has long been a go-to for any kind of repair tools, but their line of DIY pedal kits are sturdy, useful, and fun. Out of their line of kits, I chose the Fan Tremolo not only because of my fandom (sorry), but also because this circuit offers three different flavors: vintage-style ’60s, heavier ’70s style, and a pristine digital version.
This was the second pedal I had built, and I’m glad my soldering skills were proven before I started because this design needed a slightly more delicate touch. Plus, it tested my troubleshooting abilities, which is necessary no matter what kit you’re building.
Out of the box, the components were high-quality and the step-by-step instructions were clear and concise. Out of the three builds I did for this story, this was the only one that really gave me a crash course in deciphering the color bands on resistors. This is one step where a multimeter can help alleviate any doubts between brown and violet and black. After sorting all the parts, it took me most of an afternoon to complete the entire build.
My favorite setting was the thicker ’70s sound. It’s chewy and warm. Admit it: It’s nearly impossible not to break into “Born on the Bayou” when you're rocking a trem at a very specific speed. Although it had a bit more wire work and took a focused touch in certain places, the Fan Tremolo would be a solid first step for aspiring pedal builders who want to dip into modulation. Just take your time.—JS
Selenium, an alternative to silicon and germanium, helps make an overdrive of great nuance and delectable boost and low-gain overdrive tones.
Clever application of alternative materials that results in a simple, make-everything-sound-better boost and low-gain overdrive.
Might not have enough overdrive for some tastes (although that’s kind of the idea).

Cusack Project 34 Selenium Rectifier Pre/Drive Pedal
cusackmusic.com
The term “selenium rectifier” might be Greek to most guitarists, but if it rings a bell with any vintage-amp enthusiasts that’s likely because you pulled one of these green, sugar-cube-sized components out of your amp’s tube-biasing network to replace it with a silicon diode.
That’s a long-winded way of saying that, just like silicon or germanium diodes—aka “rectifiers”—the lesser-seen selenium can also be used for gain stages in a preamp or drive pedal. Enter the new Project 34 Selenium Rectifier Pre/Drive from Michigan-based boutique maker Cusack, named after the element’s atomic number, of course.
An Ounce of Pre-Vention
As quirky as the Project 34 might seem, it’s not the first time that company founder Jon Cusack indulged his long-standing interest in the element. In 2021, he tested the waters with a small 20-unit run of the Screamer Fuzz Selenium pedal and has now tamed the stuff further to tap levels of gain running from pre-boost to light overdrive. Having used up his supply of selenium rectifiers on the fuzz run, however, Cusack had to search far and wide to find more before the Project 34 could launch.
“Today they are usually relegated to just a few larger industrial and military applications,” Cusack reports, “but after over a year of searching we finally located what we needed to make another pedal. While they are a very expensive component, they certainly do have a sound of their own.”
The control interface comprises gain, level, and a traditional bright-to-bassy tone knob, the range of which is increased exponentially by the 3-position contour switch: Up summons medium bass response, middle is flat response with no bass boost, and down is maximum bass boost. The soft-touch, non-latching footswitch taps a true-bypass on/off state, and power requires a standard center-negative 9V supply rated at for least 5 mA of current draw, but you can run the Project 34 on up to 18V DC.
Going Nuclear
Tested with a Telecaster and an ES-355 into a tweed Deluxe-style 1x12 combo and a 65 Amps London head and 2x12 cab, the Project 34 is a very natural-sounding low-gain overdrive with a dynamic response and just enough compression that it doesn’t flatten the touchy-feely pick attack. The key adjectives here are juicy, sweet, rich, and full. It’s never harsh or grating.
“The gain knob is pretty subtle from 10 o’clock up, which actually helps keep the Project 34 in character.”
There’s plenty of output available via the level control, but the gain knob is pretty subtle from 10 o’clock up, which actually helps keep the Project 34 in character. Settings below there remain relatively clean—amp-setting dependent, of course—and from that point on up the overdrive ramps up very gradually, which, in amp-like fashion, is heard as a slight increase in saturation and compression. The pedal was especially fantastic with the Telecaster and the tweed-style combo, but also interacted really well with humbuckers into EL84s, which certainly can’t be said for all overdrives.
The Verdict
Although I almost hate to use the term, the Project 34 is a very organic gain stage that just makes everything sound better, and does so with a selenium-driven voice that’s an interesting twist on the standard preamp/drive. For all the variations on boost and low/medium-gain overdrive out there it’s still a very welcome addition to the market, and definitely worth checking out—particularly if you’re looking for subtler shades of overdrive.
You may know the Gibson EB-6, but what you may not know is that its first iteration looked nothing like its latest.
When many guitarists first encounter Gibson’s EB-6, a rare, vintage 6-string bass, they assume it must be a response to the Fender Bass VI. And manyEB-6 basses sport an SG-style body shape, so they do look exceedingly modern. (It’s easy to imagine a stoner-rock or doom-metal band keeping one amid an arsenal of Dunables and EGCs.) But the earliest EB-6 basses didn’t look anything like SGs, and they arrived a full year before the more famous Fender.
The Gibson EB-6 was announced in 1959 and came into the world in 1960, not with a dual-horn body but with that of an elegant ES-335. They looked stately, with a thin, semi-hollow body, f-holes, and a sunburst finish. Our pick for this Vintage Vault column is one such first-year model, in about as original condition as you’re able to find today. “Why?” you may be asking. Well, read on....
When the EB-6 was introduced, the Bass VI was still a glimmer in Leo Fender’s eye. The real competition were the Danelectro 6-string basses that seemed to have popped up out of nowhere and were suddenly being used on lots of hit records by the likes of Elvis, Patsy Cline, and other household names. Danos like the UB-2 (introduced in ’56), the Longhorn 4623 (’58), and the Shorthorn 3612 (’58) were the earliest attempts any company made at a 6-string bass in this style: not quite a standard electric bass, not quite a guitar, nor, for that matter, quite like a baritone guitar.
The only change this vintage EB-6 features is a replacement set of Kluson tuners.

Gibson, Fender, and others during this era would in fact call these basses “baritone guitars,” to add to our confusion today. But these vintage “baritones” were all tuned one octave below a standard guitar, with scale lengths around 30", while most modern baritones are tuned B-to-B or A-to-A and have scale lengths between 26" and 30".)
At the time, those Danelectros were instrumental to what was called the “tic-tac” bass sound of Nashville records produced by Chet Atkins, or the “click-bass” tones made out west by producer Lee Hazlewood. Gibson wanted something for this market, and the EB-6 was born.
“When the EB-6 was introduced, the Bass VI was still a glimmer in Leo Fender’s eye.”
The 30.5" scale 1960 EB-6 has a single humbucking pickup, a volume knob, a tone knob, and a small, push-button “Tone Selector Switch” that engages a treble circuit for an instant tic-tac sound. (Without engaging that switch, you get a bass-heavy tone so deep that cowboy chords will sound like a muddy mess.)
The EB-6, for better or for worse, did not unseat the Danelectros, and a November 1959 price list from Gibson hints at why: The EB-6 retailed for $340, compared to Dano price tags that ranged from $85 to $150. Only a few dozen EB-6 basses were shipped in 1960, and only 67 total are known to have been built before Gibson changed the shape to the SG style in 1962.
Most players who come across an EB-6 today think it was a response to the Fender Bass VI, but the former actually beat the latter to the market by a full year.

It’s sad that so few were built. Sure, it was a high-end model made to achieve the novelty tic-tac sound of cheaper instruments, but in its full-voiced glory, the EB-6 has a huge potential of tones. It would sound great in our contemporary guitar era where more players are exploring baritone ranges, and where so many people got back into the Bass VI after seeing the Beatles play one in the 2021 documentary, Get Back.
It’s sadder, still, how many original-era EB-6s have been parted out in the decades since. Remember earlier when I wrote that our Vintage Vaultpick was about as original as you could find? That’s because the model’s single humbucker is a PAF, its Kluson tuners are double-line, and its knobs are identical to those on Les Paul ’Bursts. So as people repaired broken ’Bursts, converted other LPs to ’Bursts, or otherwise sought to give other Gibsons a “Golden Era” sound and look ... they often stripped these forgotten EB-6 basses for parts.
This original EB-6 is up for sale now from Reverb seller Emerald City Guitars for a $16,950 asking price at the time of writing. The only thing that isn’t original about it is a replacement set of Kluson tuners, not because its originals were stolen but just to help preserve them. (They will be included in the case.)
With so few surviving 335-style EB-6 basses, Reverb doesn’t have a ton of sales data to compare prices to. Ten years ago, a lucky buyer found a nearly original 1960 EB-6 for about $7,000. But Emerald City’s $16,950 asking price is closer to more recent examples and asking prices.

Gibson Victory Figured Top Electric Guitar - Iguana Burst
Victory Figured Top Iguana BurstThe SDE-3 fuses the vintage digital character of the legendary Roland SDE-3000 rackmount delay into a pedalboard-friendly stompbox with a host of modern features.
Released in 1983, the Roland SDE-3000 rackmount delay was a staple for pro players of the era and remains revered for its rich analog/digital hybrid sound and distinctive modulation. BOSS reimagined this retro classic in 2023 with the acclaimed SDE-3000D and SDE-3000EVH, two wide-format pedals with stereo sound, advanced features, and expanded connectivity. The SDE-3 brings the authentic SDE-3000 vibe to a streamlined BOSS compact, enhanced with innovative creative tools for every musical style. The SDE-3 delivers evocative delay sounds that drip with warmth and musicality. The efficient panel provides the primary controls of its vintage benchmark—including delay time, feedback, and independent rate and depth knobs for the modulation—plus additional knobs for expanded sonic potential.
A wide range of tones are available, from basic mono delays and ’80s-style mod/delay combos to moody textures for ambient, chill, and lo-fi music. Along with reproducing the SDE-3000's original mono sound, the SDE-3 includes a powerful Offset knob to create interesting tones with two simultaneous delays. With one simple control, the user can instantly add a second delay to the primary delay. This provides a wealth of mono and stereo colors not available with other delay pedals, including unique doubled sounds and timed dual delays with tap tempo control. The versatile SDE-3 provides output configurations to suit any stage or studio scenario.
Two stereo modes include discrete left/right delays and a panning option for ultra-wide sounds that move across the stereo field. Dry and effect-only signals can be sent to two amps for wet/dry setups, and the direct sound can be muted for studio mixing and parallel effect rigs. The SDE-3 offers numerous control options to enhance live and studio performances. Tap tempo mode is available with a press and hold of the pedal switch, while the TRS MIDI input can be used to sync the delay time with clock signals from DAWs, pedals, and drum machines. Optional external footswitches provide on-demand access to tap tempo and a hold function for on-the-fly looping. Alternately, an expression pedal can be used to control the Level, Feedback, and Time knobs for delay mix adjustment, wild pitch effects, and dramatic self-oscillation.
The new BOSS SDE-3 Dual Delay Pedal will be available for purchase at authorized U.S. BOSS retailers in October for $219.99. To learn more, visit www.boss.info.
