completed my headtrip 2 build and it no workie. dry pot works and can hear a pop when changing patches. No effect tho. Wet pot turned all the way up. Voltage are all correct except pins 5 and 6 on the eprom read 0. Pin 14 and 15 on the FV-1 are both 3.3vdc but 5 and 6 on the eprom are 0. The pads for pins 5 and 6 on the eprom read 0 as well. According to the schematic they should match pin 14 and 15 on the FV-1 and there is nothing between the FV-1 pins 14 and 15 and eprom pins 5 and 6. Checked for continuity between 15 and 5 and between 14 and 6 and it reads good. Where did the voltage go?
One additional note. The volume of the popping when changing patches is controllable via the wet pot (the wet pot seems to be working but no effects.)
update: tracing the signal and found it dropping out at R4. R4 reads 10k. Not sure why signal is lost there. it's on one side but not on the other.
with the tails switch on the signal is present at pin 1 and 2 of the FV-1 but not on 28 or 27. It's not coming out of the FV-1.
