A friend of mine has been begging me to modify this thing to see if I can get rid of the mud. I can't find much info on it except that it's cheap. I was thinking about changing the input caps a size smaller, maybe fiddle w the tonstack some and change the diodes. Is there much else I can do to it?
supposedly an OCD clone, modded by Freekish Blues to be their Alpha Drive
