Iron Butterfly Fuzz Wah

Not much info on this one, not even who actually made it. Found the schematic years ago over at DIYSB where it was reversed with the help of none other than dino. Figured I'd tale a shot at a vero since I did so many other wahs.

Standard Hemmo Fuzz/Booster w/ mods

Found an old schematic of Standard Hemmo Fuzz, which has two outputs. One for cleanish boost and second for fuzz. Drew it as described and added diode clippers as notes suggested. Added volume pots for both modes, 2PDT stomps for mode select and basic bypass. Some of you might find this rather usable...

Systech Overdrive

Here is a simple layout for a nice pedal from the 70's.
The schematic I've used is available here.

Spaceman Sputnik II

"Starting with the same germanium transistors as the much-loved original Sputnik, but with slightly different specs, we added a few slight tweaks to get very close to the sonic details of the original circuit. Many of the other parts in the Sputnik II are different but of same or similar value, including many vintage and rare parts.
While extremely similar to the original, the Sputnik II is a beast all its own. The Sputnik II takes everything we loved about the original, and adds in the things we dreamed of after its original release it:
• Full-size control knobs for every parameter
• Foot-switchable DRIFT mode, with its own status indicator
• Additional FILTER options for maximum tone-shaping
• Additional circuitry making it more friendly to active pickups, buffers, synths, pedals, etc
Within Sputnik II lies a plethora of fuzz tones. Smooth, gritty, vintage, modern, thick, thin, buzzy, bassy, splatty, sputtery, noisy, buttery, controlled or very much out-of-control. A truly endless cornucopia of fuzz."

Here is another pedal reverse-engineered by Dino (Digi2t).
He also added an extra diode reverse switch.
For all infos on how to build this pedal you can find Dino's original thread (with his own vero) and schematic on the DIY forum here.
