Hi MrFixr55, Thank you for the drawing. I can handle that. I disconnected the muting switch from the center pin of the pot so that rules that out. While I was there I measured the pot and found it is 2.7 meg vs the 2 meg the schematic says. I had a junk 2 meg pot with the 1 meg tap that I swapped in but it made no difference.
