I am not getting any wet signal from FV-1. I checked Tl074 and it works fine, I've also tested if the signal passes from pin 28 of FV-1 to the output (probed guitar signal directly to pin 28). I also made sure pins are not shorted and that 3.3 V is supplied. I assume oscilator might not be working or the FV-1 is is bad (both were bought from Musikding). Also EEPROM is not connected.
Edit: when I touch program select switch I can hear a loud pop coming from my amp.
