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
MXR Distortion III
Being so similar to Wylde Signature and GT-OD, i can understand why this one was still missing from the library. Well. Up the 100n to 220n-1µ from inverting input of the driver amp to VRef and swap the clippers for LEDs. Should be worth your while…
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
HPF Technology HPF-Pre 2
I’ve had a few folks asking for active bass cutter circuit for couple of different uses. First, a lot of stoner rock enthusiast want to split their signal for two amps and some blues folks want to do that too. And since in cases like these, the second amp is usually a guitar amp, which … 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
