One of the classic distortion boxes found in the Distortion Hall-of-Fame! Raw, fuzzy distortion and lots of volume can be pushed out of this sucker!
Built it; sounds like a Rat ;)
There are lots of schematics out there to build the Rat. Som of them excellent, some really bad. I've chosen this schematic as it seemed 100% (vintage) correct.
I based this layout on this one found on the website of Aron Nelson and modified it to fit nicely in a B enclosure.
Ruetz mod: just remove R8 and/or C4, or replace R8 with a 1K pot.
Booster: remove the clipping diodes D2 & D3.
You can also experiment with different kind of clipping diodes like symmetric/asymmetric setups, LED's, Germanium diodes, etc.
