Thanks for your help. Would this all be done with a multi meter and then an audio probe?
how do you connect phone to pedal?Yes. Digital Multi Meter set on DC voltage set to a range higher than 9V. Then you need a signal generator (I use a phone app) into the input and look at the sine wave oscilloscope, which is set to 1ms at .1 V on the AC setting. I check the input and out put of the devices, folloing the schematic.

I just use audio--no oscilloscope necessary. What oscilloscope do you use?
Double check EVERY component… make a habit of troubleshooting thoroughly and it will save you a lot of head scratching down the road when you take on more complex projects and things go sideways.I didn’t check every resistor
I built an audio probe a while back and run music through it with my phone. So it will work in this case, if i look for where the signal gets weak? Is there any certain spots to check or am i hunting and pecking around?Audio probe is helpful here. Do you have a looper pedal? If so capture a riff and put in on repeat into the pedal. Then start probing. You'll have to start tracing the audio path from the input to the point where it gets weak.
If you don't have a probe they're dirt simple to build.
Try to follow the signal path in the schematic. It should be pretty straight forwardI built an audio probe a while back and run music through it with my phone.

Thanks im gonna give it a shotStart by measuring at the ins and outs of all the components along this path.
At the start it should pretty much match the input signal--at some point you'll read a point where it doesn't, which will give you more clue as to which part of the circuit is misbehaving.

Resistors are important too.Checked everything but the resistors
