    8.97v in to 8.25v out across D4, then another drop 8.25v in to 7.08v out through R28. I’ll try resoldering D4 and R28 tomorrow and see if that helps.

    D4 seems fine I’d try reflowing R28

    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!

    Great glad it’s sorted

    If you haven’t already make yourself an audio probe They’re cheap and easy to make and use

    Probing your circuit cuts down debugging from hours to minutes most times

    It’s a great tool
