Just happening now.  Doesn't matter what pedals I have in the loop.  I haven't touched anything since I initially completed the build. I've let the pedal sit unused on a shelf between the time of initial successful testing and now.

Ok Ive just received a reply from Peter..

My original design did use a buffer for the bias voltage, but it had some major issues. It's been so long since I was at that part of the design phase, so I can't remember exactly what the problems were. I just remember that when I abandoned the buffered bias and went to a simple voltage divider using 1k resistors, it worked great.

I'm still going to move forward with the buffer board.  As an engineer, it makes sense to me, and I cannot see a scenario where it would cause a problem.  Of course, I need to fix other things before I move forward.

Haven't cracked it open yet.  Maybe tonight I will reflow all of the pots and switches.  Hoping that's all I need to do.

For your sake, I'm hoping that's the case as well.

Haven't worked on it.  Focusing on a couple other projects at the moment.
