Pot didn't seem to make a difference. I did notice that pin3 was actually slightly lower, 4.11 while all the others were 4.30V so i need to trace that back. It really seems like that 33k is where its completely dying. Anyone think of anything why that might happen? No pots seem to work except for the volume but the usable sweep is only about 20 degrees at the upper end, then the output completely disappears.
