Green Russian Big Muff

Green Russian Big Muff

Project description

The famous Green Russian Big Muff based on the schematic at General Guitar Gadgets.

I've used this layout twice in combination with the Fet Blender for a really fat bass overdrive!


Lift the ground connection of C11/R18 to bypass the tonestack. This will add more volume and more mids.

Green Russian Big Muff

Can someone tell me how to hook up the Footswitch?
Thank You

Tall Font of Bubble Font?

Do you know if this is a "Tall Font" or "Bubble Font" version? 2nd or 3rd revision?

According to the schematics

According to the schematics on Kit Rae's site, this will be the Bubble Font because it uses 470pF capacitors. The Tall Font uses 500pF instead which makes it smoother.


This came right together and sounds as nasty as it should. Thanks for the layout!


That's what I thought but in the picture it almost look as if there's a cut there. Thanks for the help. I'll post my results.

Layout ?

Is there a trace cut under C14?


... wouldn't make sense too since C14 is placed vertically on the edge of the board.
