Simple Theremin

A recent request that caught my eye, a fairly simple theremin project. I've always found these to be neat with tons of possibilities when combined with other effects. The project was posted over on Instructables.

Original without Regulator

With Regulator

Nine Volt Nirvana Dino Drive

Another fuzz from Nine Volt Nirvana, Joe Gagan. It's another modified Fuzz Face, and from the one video of it, it sounds bad ass.

Wampler Hot Wired v.1

Original FSB thread and schematic available here.
These are 2 separate effects in one box.
Follow Mark's Dual Offboard Wiring.
23/11/2017 Layout Updated! Added the 2 Inputs caps.

Guyatone PS-021 Guitar Exciter / Compressor

A vintage pedal from the 80s.
I've removed the flip flop switching system and buffers (thanks Zach for the help).
Hopefully it will fit in a 125B box.
You can find original thread and schematic here.
Updated schematic is available in our Forum section. 
Thanks Dino for his explanatory video.
12/11 Layout Updated! Readded the input buffer as Aion's suggested.

... and the LM13700 version

VFE Pedals Dragon Hound

"The DRAGON HOUND is a dual overdrive + distortion pedal that combines the core circuits from the Alpha Dog and Pale Horse into one unique dirt box. Each circuit has a dedicated drive control, and the blend control can dial in saturated distortion tones that retain the clarity of an overdrive."
You can find their original pedal (now discontinued) on their website here and the original schematic here.
