Lovepedal Purple Plexi 800
Here’s another Lovepedal circuit. It’s similar to the Black Magic, adding a frequency control, and is supposed to sound like a Marshall amp.

Fairfield Circuitry Barbershop Overdrive
This one was a request. Two pots onboard and one offboard. The Barbershop Overdrive is a transparent overdrive/booster with medium gain. It has the expected Volume and Drive controls, but also has a Sag control which alters the voltage the pedal is running at. This can change the color and compression of the tone. UPDATE: … Read more
Zvex Box of Rock
This layout is for the distortion side of the Box of Rock. The Boost side is just a SHO. I’ve laid this effect out for top mounted pots like in my other Zvex layouts and should fit vertically in a 1590B. Pots are 1.1 inches (28mm) apart. Board dimensions: 3.2 x 1 in. or 81.3 … Read more
Zvex SHO – Crackle Okay
The Zvex Super Hard On has become one of the sought after boost pedals today. Derived from the preamp section of a 60s recording console, the SHO uses negative feedback to control the gain (which is what gives it the crackle when adjusting the knob). It’s capable of being a clean boost and adding some … Read more
Lovepedal Les Lius
One of Sean’s many Electra Distortion variants, the Les Lius delivers both Tweed Deluxe and Fender Twin tones. The 3-way toggle switches between different clipping options and the 2nd footswitch acts like a separate gain channel. I couldn’t find much info on what JFET is used for Q2, but I would imagine any DSG pinout … Read more
Lovepedal Eternity
The Eternity Overdrive is kind of like the Big Muff of Lovepedal in that it has a ton of different versions (there are over 10 I believe), but it’s basically a Tube Screamer without the input/output buffers. I’ve drawn up 2 versions here, the Black and the Burst. The main difference between the 2 is … Read more
Ripthorn FET-2B Bass Preamp
DIYStompboxes forum member Ripthorn adapted the Alembic F-2B tube preamp to a JFET preamp. It gives you 3-band EQ controls, master volume, and a bright switch. Fairly simple circuit, but might turn into a bit of a rats nest with the offboard wiring (I know, a bit out of character for me). Set the trimmers … Read more
Pearl/Vorg Warp Sound
Here’s a rare one that came in via the request folder. It’s a distortion/filter effect. Used live by guitarist Kevin Sheilds from My Bloody Valentine on “Sometimes,” this might be a must-build for shoegazer fans out there. Here’s a demo video of a clone with the 100k trim pot wired externally as a distortion control … Read more
EHX Big Muff – Green Russian
With the exception of the IC BMP (’77, ’78) you can theoretically build just about any version of the Big Muff on any other version’s layouts, but the values listed in this one are for the Tall Font Green Russian version. This one is smaller than the BMP layout I did with on board pots … Read more
Bikini Wax
Nocentelli’s Bikini Wax is a shaved down Big Muff with the tone control and gain recovery stage removed. Play around with transistors and especially diodes to change the tone to your liking. Update 3/16/15: Since the layouts for the Green Russian Big Muff were derived from this one, and the Green Russian was missing a … Read more
