Hello everybody,
I have a mark bass s450 "club series" on the bench right now with a weird problem: the gain knob is crackling and the more you turn it up, the lower goes the amp's volume; when gain is maxed the amp is dead silent.
I tried to trace the board but it looks like a 4 layers board with lots of points going nowhere, so i'm here asking if anybody has a schematics for this beast.
