Jon Patton's Clipper Ship
Jon has contributed a lot to the DIY pedal building community and I always learn something new when I layout one of his circuits. So I think we'll have a Jon Patton week, starting with the Clipper...

Jon Patton's Blue Warbler
Continuing Jon Patton Week with a vibe/tremolo effect called the Blue Warbler. It features envelop control over the LFO and can be built with one or two LDR stages (layout below reflects the 2 stage...

Jon Patton's Mossy Sloth
Finishing out Jon Patton week with the Mossy Sloth Fuzz for Fuzz Friday. It's a pretty unique transistor-based fuzz and uses MOSFETs to create some asymmetrical clipping for some unusual fuzz and...

JHS Angry Charlie
I've gotten a few requests to redo the MI Audio Crunch Box with board mounted pots. How is that relevant to the Angry Charlie you ask? Well, it's the same circuit. JHS added a cap in parallel with the...

MXR Custom Badass '78 Distortion
I've wanted to draw this one up for a while. It's a fantastic clone/variation of the  Boss DS-1 Distortion. I had one for a while and loved it, but ended up selling it to fund some other stuff. But I'm...

Dunlop Band of Gypsys Fuzz Face
Here's the Band of Gypsys Fuzz Face from Dunlop for Fuzz Friday. Despite being called a Fuzz Face, the actual circuitry of the Band of Gypsys version isn't even close to the original Fuzz Face. It's...

Tortenmann TA-100
Came across the schematic for this and thought it would be a good addition. It's a unique germanium overdrive using PNP AC128s, though the effect is a negative ground effect (so it can be daisy chained...

Simple CabSim
Came across this design in researching a different project and thought I'd draw it up. It uses 3 transistors and doesn't take up a lot of space, so you should be able to fit it in a 1590A or add it to...

Frantone The Sweet
Laying out Big Muff variations never gets old for me. This one uses germanium transistors in the two clipping stages (and predates the EQD Hoof which also uses germanium transistors) along with...

JHS Charlie Brown V3
Unrelated to the Angry Charlie circuit, the Charlie Brown emulates the brown sound of a JTM45 amp and is a variation on the zVex Box of Rock without the boost section. The input stage is an AMZ Mosfet...

Throbak Overdrive Boost
Pretty much a Colorsound Overdriver clone. Laid this out for a 125B (because of the dual footswitches) with board mounted pots. The boost footswitch bypasses the PreGain pot and only uses one side of a...

Field Effects Acceleron Fuzz
Here's a pretty unique fuzz for Fuzz Friday–the Acceleron from Field Effects. It uses a mix of BJT and JFET transistors and offers a wide range of fuzz tones. I've laid it out for board mounted pots...

Friedman BE-OD
By popular demand, here's the BE-OD from Friedman, one of the best Plexi in a box pedals around. Well, not Plexi really. It's designed to emulate the Friedman Brown Eye tube amp head. Laid this one out...

Colorsound Tremolo
Haven't done a tremolo in a while, so let's remedy that with the original 4-transistor Colorsound Tremolo (the re-issue is the 3-transistor version). Originals used 2SC945 transistors (BCE pinout), but...

Death by Audio Kill Kill Filter
It's a Fuzz and Filter Friday! Here's DBA's Kill Kill Filter. At it's heart is a stripped down Big Muff (only one distortion section without clipping diodes) with a footswitch selecting 2 different...

Valve Wizard Engineer's Thumb
A little blog update: You may have noticed there wasn't a post yesterday and that there is one today. Why on a Tuesday and not a Monday? Some big-ish changes are coming to the site in the near future,...

Escobedo T.M.K.
Here's a really cool one designed by the great Tim Escobedo. T.M.K. = Too Many Knobs. (And you thought the Fuzz Factory had too many) It's part fuzz box, part noise maker and would probably be just as...

TC Electronics Spark Mini
Here's a work-a-like for the Spark Mini. It'll be a bit of a squeeze, but it should fit in a 1590A. The original is all SMD components, so the transistors listed below aren't the same as the original,...

Wampler Sovereign
Here's another Wampler take on the JFET mu-amp design. This one adds a op amp stage at the output and features a Big Muff-style tone stack. This one's pretty versatile and a great sounding distortion....

Pladask Delay V3
Don't know much about this one. Stumbled across it on the Tagboard forum and thought it was an interesting design. It can apparently do normal delays as well as some lofi craziness. Schematic and...
