I've built a Prometheum Distortion HM2 clone and theres a 11.5KHz whine, the other one i built doesnt have this and its still present with a battery and with the gain knob down, does anyone have any ideas? i checked the chips and they all work fine. The whine seems to be coming into the circuit after c1.
