D*A*M Ezekiel - weird issue

[jonnygreentrees]

Just built the DAM Ezekiel for a friend and I'm having the weirdest issue.

The first time after you connect the power and engage the effect there is no sound - however if you play a low chord aggressively the effect springs to life and then you can happily switch the effect on and off as normal and it works fine.

If you disconnect and reconnect the power the issue reappears - play a loud chord, effect starts working, effect works normally until you remove and reinsert the power again.

Any ideas?

I am testing with a guitar if that matters

Sorry here's some more information:

Schematic and info here:

I've built it on the PCB from FuzzDog.

The problem is there no matter which set of clipping diodes I have selected which suggests it might be an issue with the IC?

Probably an electrolytic issue, backwards or poorly soldered.

Thanks, I did wonder if it was a capacitor, I'll double check them all tonight

sorted - it was a bad IC chip
