Basic Audio Scarab Deluxe
This is a variation of the Mictester Silicon Tonebender, which is based of the Tone Bender Mk II Professional circuit. John Lyons was kind enough to shed some light on his version over at FSB.

Earthquaker Devices Crimson Drive (2-knob version)
Here’s a good sounding overdrive from Earthquaker Devices. This is for the first incarnation of the Crimson Drive with just level and gain controls. Uses a J201 in a buffer stage and a PNP AC128 in the gain stage. Dirk_Hendrik from FSB traced one and drew this schematic. The power filter section makes me scratch … Read more
Simple Transistor Compressor
FSB member Mictester came up with this design a couple years ago. Utilizes 4 transistors, 1 PNP and 3 NPN, though you could probably use an NPN in place of the PNP. Best to socket and try a few different transistors. The schematic says BC213L for Q1 and BC183L for Q2-4, but any medium gain … Read more
Rockett WTF
Mmolteratx traced this one over on FSB. Figured I’d put it up. Seems to be a BossTone derivative with some tweaks. Here’s the original: And since all the offboard wiring is making a few people say, “WTF,” here’s the rat’s nest that is the offboard wiring for this effect. The “In” and “Out” wires go … Read more
Electro Harmonix Ram’s Head Big Muff
There are a lot of versions and subversions of the Big Muff. Many consider the Violet Ram’s Head to be the best, though many consider the Triangle, or IC, or Green Russian, etc. the best. YMMV This one has the pots hard mounted to the board, though depending on the enclosure you use, it may … Read more
Zvex Wooly Mammoth
The Zvex Wooly Mammoth is a Fuzz Face derivative designed for bass, but sounds awesome on guitar as well. For this one I’ve laid it out for on board pots oriented like the originals. On the PCB I added an LED and LED resistor for on/off indication. As with my layout for the Fuzz Factory, … Read more
ProCo RAT (’86 version)
Since I did the Blower Box yesterday, and it’s essentially a RAT, I figured it wouldn’t take too much effort to convert that layout to the original. So here’s the original ’86 RAT.
Idiot Box Effects Blower Box
Here’s a pretty cool bass distortion based on the RAT. The normal filter section on a RAT is replaced with a passive baxandall network. It was traced by FSB member p.eat and the schematic I based this layout from was drawn by johnk.
Run Off Groove Odie
Here’s the Odie from Run Off Groove. It’s an alternative to the Tube Screamer using JFETs. Be sure to adjust the drain trimpots to 1/2 the supply voltage. Sound clips can be found here. This one is verified (and sounds fantastic). Here’s a few pics of my build.
Univox SuperFuzz (stock)
Here’s a layout for the stock Univox SuperFuzz. I probably should have drawn this one first and then the modded one below, but it was actually easier to take the modded layout and reverse it back to stock.
