DIAMOND: Fred Briggs Diamanté Compressor

Fred Briggs Dimante Compressor vero layout v1 60f64073735b

I was looking at the Diamond Compressor schematic the other day and thought it looked interesting and possibly something that could be simplified – it turns out it can be simplified.  Of course, someone had already done this.  Jump over to the La Revolution Deux for details, AKA Fred Briggs’ blog.   I used a TL074 instead … Read more

BJFE: Folk Fuzz 3.5%

I’ve not tried any BFE circuits, so perhaps it’s time…    The link to the schematic is here.  Transistors can be germanium or silicon, and the two acting as hard clipping diodes can probably be replaced with regular silicon diodes to taste (the blue ones).    BJFE FOLK FUZZ 3.5% – VERO LAYOUT

EARTHQUAKER DEVICES: Disaster Transport Jr, with mods

This is the standard Disaster Transport Jr, with the tails mod, and another that I just found that adds a kind of chorus effect to the delay, with just an additional resistor. A Disaster Transport layout seems fitting, as there’s been widespread flooding where I live, so kind of appropriate for the weather. Here’s the link to … Read more

DINOSAURAL: OCT-201 Opticompressor

Another day, another compressor layout…  This is a Dan Coggins design, the Dinosaural OCT-201 Opticompressor, and the predecessor to the Thorpy Fat General, which was also designed by Dan. Not many of these are around, as it was only made in a short run. Schematic and tracing journal on Aion FX. DINOSAURAL OCT-201 OPTICOMPRESSOR – VERO … Read more

THORPY FX: Fat General Optical Compressor

THORPY FX Fat General vero layout v1c 4163625588f7

While on a run of compressors, I thought this one looked interesting.  ThorpyFX Fat General is an optical compressor with a treble control and a blend function. Schematic can be found on PedalPcb here. It’s said to be a progression of the Dan Coggins designed Lovetone OCT-201 – based on the trace at Aion FX,  … Read more

ZVEX: Machine

This is an interesting one – the Zvex Machine uses Mosfet boosters into a pair of transistors in a push-pull configuration designed to generate cross-over distortion.  Apparently, it doesn’t do much on its own but likes to be paired after a fuzz to shine.
