tuning knob not working

by frey on Tue Mar 06, 2007 12:39 am

x0x #444 is almost completely working, flashing lights and lovely noises.

I've managed to tune it using the two trim pots but the tune knob (VR2) isn't changing the tuning. I've checked for bridged solder connections but can't find any..

anyone have any pointers to help me fix this?

its possible that the pot is bad
measure the resistance
between its pins
