Green Russian Big Muff
Posted Wed, 2009-09-09 21:24 by Harold
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!
Mods
Lift the ground connection of C11/R18 to bypass the tonestack. This will add more volume and more mids.

Green Russian Big Muff
Submitted on March 5th, 2013 by AnonymousCan someone tell me how to hook up the Footswitch?
Thank You
Tall Font of Bubble Font?
Submitted on October 30th, 2012 by AnonymousDo you know if this is a "Tall Font" or "Bubble Font" version? 2nd or 3rd revision?
According to the schematics
Submitted on April 20th, 2013 by AnonymousAccording 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.
Verified!
Submitted on July 4th, 2012 by AnonymousThis came right together and sounds as nasty as it should. Thanks for the layout!
Right!
Submitted on June 28th, 2012 by AnonymousThat'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 ?
Submitted on June 28th, 2012 by AnonymousIs there a trace cut under C14?
Nope
Submitted on June 28th, 2012 by admin... wouldn't make sense too since C14 is placed vertically on the edge of the board.
