| R.G. | Re: Circuit problem... Whine is oscillation. Ground problem is a good guess; slight mis-wiring is another one. 25K for 22K is fine. Try reading the DC voltages at all the pins of the transistors and opamp and reporting them back here - that's the best first step to debugging this one. You don't mention - does the guitar sound come through? |
