Devi Ever Shoegazer

 Had a request for this one...yes I know it is a Soda Meiser into a Thorns Peaker and could be built on separate boards but...those small Devi circuits is so much fun to draw.😏

Note that it is highly recommended to use a 10k pot for Sustain to avoid noise and dead spots in the sweep.

Dead Air Face Disaster

 Phew, February has been a wild month here on the blog so lets end it with a BANG. This one is based on Tim Escobedo's DIY classic, Ugly Face with quite a few added bells and whistles such as a optical LFO section, separate starve control for two of the chips and some tweaked values here and there.

EarthQuaker Devices Dream Crusher

 Traced by Unsound Circuitry, once again, thanks, mate!

It is a well known fact that this is a modified Ge Fuzz Face. The stock Fuzz control is ditched and replaced with a "Pre Gain2 control. It runs on normal power supply and is powered by soviet MP37B NPN  germanium transistors. These are usually faily low gain and the current leakage is low. The bias trimpot is placed on the side of the board for easy moddong for an external bias pot.
