Re:: PG series synth guitar increased volume output mod

No, I didn't have anything suitable on hand at the time, so I just used a range of resistors with alligator clips for quick testing. I started with a 470 ohm resistor on the synth line in parallel with the 2.2k board resistor - the output was nice and loud, but at the maximum and mnimum positions on the synth volume pot, a high pitched digital sounding hum crept in. Funny that if you turned the knob to just off max or min, the noise disappeared. When I tried a 1.5k resistor, the noise disappeared but the volume was still increased - not quite as much as the 470 ohm, but close to it.
