PedalPCB

PedalPCB is a supplier of do-it-yourself guitar effect circuit boards. What it sells is the bare printed circuit board (PCB): the builder buys the board, solders on the resistors, capacitors, transistors and controls, houses it in an enclosure and wires the jacks and footswitch. Most of the catalog is built around circuits that compare to well-known production pedals, and each product page names the pedal a board compares to, along with a disclaimer that PedalPCB is not affiliated with that maker123.

The range covers fuzz, overdrive and distortion most heavily, plus compressor, tremolo, boost and preamp boards, and a small number of PedalPCB original designs. Boards are priced individually, from $8.00 for the Dream Fuzz to $15.00 for the Proposition Distortion as listed on PedalPCB's product pages in October 20264.

What PedalPCB sells

The core product is the effect PCB, but the catalog also includes hardware that helps a builder finish a pedal:

  • Effect boards for fuzz, overdrive, distortion, compressor, tremolo, boost and preamp circuits4
  • 3PDT breakout boards for wiring the footswitch, in standard and illuminated versions67
  • A ProtoBoard, an integrated prototyping board for working up your own circuits8
  • A Permanent Breadboard, 3.3 x 2.1 inches, for solderless-style experimentation9
  • Faceplates, such as the Low Tide Faceplate designed to fit a 1590BB enclosure10

Each effect board's product page gives the circuit it compares to, the controls, the target enclosure, the board's dimensions and weight, and a trademark disclaimer naming the original maker4.

Boards, enclosures and sizing

Enclosure choice is the first practical decision for a PedalPCB build, and the product pages state the target enclosure for many boards. The 125B with top-mounted jacks is a common layout in the range, used on boards such as the Curds and Whey Distortion, Virile Boost, Dung Beetle, Minidrive, Circulator, Jet Drive, Kalle, Pacifier, Octanaut, Dream Fuzz, Acid Rain Fuzz, General Tso's Compressor, Chickenhead, Woodpecker Tremolo, Viceroy Overdrive (Boneyard Edition), EVPreamp, and Fuzz Foundry; larger circuits call for a 1590BB, as on the ElectroVibe and Arkaim Fuzz111213.

Arkaim Fuzz1590BB, top-mounted jacks1.95 x 3.0875 x 0.5 in0.395 oz18

Other boards follow the same pattern: the Curds and Whey Distortion, Virile Boost and Dung Beetle are designed for a 125B with top-mounted jacks, while the ElectroVibe is designed for a 1590BB19121320. The UniCab, a cab-simulation board that compares to the DSM OmniCabSim, measures 1.95 x 2.25 x 0.5 inches19.

The 3PDT breakout boards, used to wire the bypass footswitch, are tagged for 125B, 1590A, 1590BB, 1590DD and 1590XX enclosures, in both standard and illuminated single-color versions67.

Fuzz boards and the circuits they compare to

The fuzz range is where PedalPCB's "compare to" approach is most visible. Each page names the production pedal the circuit follows:

PedalPCB boardCompares to
Dream FuzzEHX Op-Amp Big Muff Pi (Reissue)4
Fuzz FoundryZVEX Effects Fuzz Factory15
Fuzz CadetEQD Fuzz Master General3
ChickenheadD*A*M Red Rooster14
Arkaim FuzzMountainking Megalith18
Sandblaster FuzzOKKO Holy Grit21
B-Side FuzzMid-Fi Demo Tape Fuzz21

The Dream Fuzz carries a single Volume control in its listed control set4. The Chickenhead is a fuzz/boost circuit with a Boost control14. The Arkaim Fuzz is a two-footswitch build, with a Bypass switch and a separate Heavy switch, plus an Output knob18. The Fuzz Foundry is a five-knob fuzz with a Volume control among them15.

The Acid Rain Fuzz stands apart from the rest of the fuzz range: PedalPCB describes it as a PedalPCB original, with Volume, Sustain and Treble controls in a 125B layout22.

Overdrive and boost boards

The overdrive side of the catalog includes the Viceroy Overdrive (Boneyard Edition), which compares to the EQD Monarch Overdrive and carries Presence and Treble controls plus an Active/Bypass footswitch23. The Proposition Distortion is based on what its page calls the legendary and extremely rare Rockman Ultimatum Distortion Generator, with a Volume control among its listed controls5. The range also includes the Irrlicht Overdrive, Virgil Overdrive and Browbeater Overdrive boards242526.

For clean level, the Virile Boost is a boost PCB designed for a 125B enclosure with top-mounted jacks12, and the Episode Booster rounds out the boost offerings12.

Compressor, tremolo and preamp boards

The General Tso's Compressor compares to the ThorpyFX Fat General and sits in PedalPCB's Dynamics category. Its three controls1727:

ControlFunction
SustainCompression control17
TrebleTone control17
BalanceOutput level control17

The Woodpecker Tremolo compares to the EQD Hummingbird, which its page names in full as the Hummingbird Repeat Percussion Tremolo. Its controls are Depth for the intensity of the tremolo, Rate for the speed of the LFO, Level for overall output volume, and a Mode toggle that switches the LFO range between slow, fast and medium16.

The EVPreamp is a preamp board comparing to the Uni-Vibe Preamp, with a single Volume control, designed for a 125B enclosure with top-mounted jacks1228.

Original circuits and affiliation

Most PedalPCB boards follow existing designs, but not all. The Acid Rain Fuzz is a PedalPCB original, and the page notes there is not a lot of info available beyond the board itself22.

PedalPCB product page22

Because so many boards compare to named production pedals, PedalPCB carries a disclaimer on each relevant page. The company states it is in no way affiliated with EarthQuaker Devices, ZVEX Effects, ThorpyFX, Mr Black, D*A*M (Differential Audio Manifestationz) or Mountainking Electronics, and that these products are not manufactured or distributed by the original makers41517162618.

PedalPCB sells bare boards, not complete parts kits. If you want a kit with the components included, a separate DIY maker, GuitarPCB, sells boards and kits through authorized distributors: PedalPartsAndKits in the USA, Das Musikding in Europe and PedalPartsAustralia in Australia293031.

Questions

Is PedalPCB affiliated with the pedal makers it compares to?

No. PedalPCB states plainly on its product pages that it is in no way affiliated with the makers whose circuits its boards compare to, including EarthQuaker Devices, ZVEX Effects, ThorpyFX, Mr Black, D*A*M and Mountainking Electronics. Each page also notes the product is not manufactured or distributed by the original maker.

Does PedalPCB sell full kits with parts?

PedalPCB's product pages list bare circuit boards, priced individually, along with helper boards like breakout and protoboards. The pages do not sell complete parts kits. A separate DIY board maker, GuitarPCB, sells boards and kits through authorized distributors: PedalPartsAndKits in the USA, Das Musikding in Europe and PedalPartsAustralia in Australia.

What enclosure does a PedalPCB board fit?

Most PedalPCB effect boards are designed for a 125B enclosure with top-mounted jacks, including the Dream Fuzz, Woodpecker Tremolo and General Tso's Compressor. Larger boards like the Arkaim Fuzz and ElectroVibe call for a 1590BB. The 3PDT breakout boards fit 125B, 1590A, 1590BB, 1590DD and 1590XX enclosures.

What pedal is the Woodpecker Tremolo based on?

The Woodpecker Tremolo compares to the EarthQuaker Devices Hummingbird, which PedalPCB's page identifies as the Hummingbird Repeat Percussion Tremolo. Controls are Depth, Rate and Level, plus a Mode toggle that switches the LFO range between slow, fast and medium. PedalPCB is not affiliated with EarthQuaker Devices.

What is the General Tso's Compressor based on?

The General Tso's Compressor compares to the ThorpyFX Fat General compressor. It is a dynamics board with Sustain, Treble and Balance controls, designed for a 125B enclosure with top-mounted jacks. PedalPCB states it is not affiliated with ThorpyFX.

Does PedalPCB have original circuits?

Yes, though most of its catalog compares to existing pedals. The Acid Rain Fuzz is described by PedalPCB as a PedalPCB original, a fuzz with Volume, Sustain and Treble controls in a 125B layout. The rest of the range is largely built around circuits from other makers.
