Good news is parts of the circuit are doing what they’re supposed to do e.g. the voltage divider R29 and 30 is halving the voltage and IC3 is working regulating the voltage so as is normal its more than likely something simple like one or more dry solder joints
Well after reflowing solder of the components in that pathway and even replacing some of the resistors, it still didn’t fix the problem. Then today as I was about to shelf it I decided on a whim to just start pressing on different components while playing through the pedal and found the culprit; It seems C4 had a band solder joint as when I moved it the effect started working.
Thanks for all the troubleshooting suggestions guys!
