Since this is most likely a audio potemeter, it will have logaritmic curve. When you use the wrong pin for ground the curve is wrong, and it will be very hard to adjust the audio level conveniently. I think you may want to put some wires on the board swapping pin 1 and 4. Volhout Yes, I agree, that appears to be what has happened. It works because we are only using half the pot. but I'll have to experiment to see if it works better with 1 & 4 swapped. Best wishes, Tom
