What a great sounding pedal.
But, after about 20 minutes or so it develops a harsh buzz along with a degraded effect. Kind of sounds like a battery needing replacement. I have tested this with a fresh battery, my Voodoo labs power supply, and a 9volt battery wired to a DC jack. When it is in buzz mode, there is no difference between the power supplies. Give it a rest and it is back to working great for 20 minutes or so.
Could this be bad op amp?
Any other thoughts?

If I had to guess based upon that description, I'd say that one of the two op amps is acting up when it's fully warmed up.

Haley with BYOC is great. She is shipping (2) tested replacements. What a great company and forum. I'll post back when I get them installed and the pedal is making magic again.

I also had them powered for about 5 hours straight just to be safe.
