[QUOTE="AuMan, post: 469278, member: 2670"] The tone is quite simple, there is a lone trimmer on the audio board. Use a 50 or 100k pot in its place. The gain however is done on a double sided 4 layer board that gets attached to the main board along with a bunch of other stuff on the main board to make it work properly. Sorry, no schematics, secret herbs and spices ;) You might find some drawings scattered across the net, but they are full of errors. Proceed at your own risk.. AuMan [/QUOTE]
