TC Electronics Spark Booster

 Schematic is avaiable HERE.

TC Electronics Mojo Mojo Overdrive

 Per request.

The layout stays mostly true to the schematic. One half of the op amps was unused to I used it for buffered Vref which doesn't hurt. Quite an interesting design if a bit over engineered.:-)

Boss SD-2 Crunch Channel

 Per request.

Schematic is avaiable HERE and a verified layout for the Lead Channel is avaiable HERE.

Grind Custom Fx Spasm Chasm

 By looking at the component values, this appears to be a smoother, tighter, civilized and mid oriented Muff variant especially when you compare it to Ultrastoner and TSM680...

Danelectro D2 FAB Overdrive

 Schematic is avaiable HERE.

Danelectro FAB Distortion

 Based on Maxon Distortion Master but with a hardwired bass control and different component values along the signal path. The buffered bypass swithing wasn't included in the schematic so I left it out.

 

 

Ltava Fuzz Wah - modified

 The fuzz and wah section of Ltava Fuzz/Vibrato/Wah multi effects pedal manufactured in Ukraine in the early 80s. The LFO section was left out simply because the layout would be too big. The internal trimpots is taken out on the outside for external gain controls. And a onboard voltage inverter was added.
