SOLVED ADHD - squeal? Ish?

[Lytt Effects]

Ok, not exactly sure how to describe what’s going on, but basically my most recent build (newest iteration of ADHD w/ enhanced bypass board) is making a high pitched squealing noise. When pedal is in True Bypass mode, the noise only occurs when the pedal is engaged. When the pedal is in Buffered Bypass, the pedal makes noise at a much lower volume when bypassed, and then gets much louder when engaged. In all instances, the guitar comes through. Sounds perfectly normal when in TB, and sounds just fine when engaged, but the noise is very present.

I have not tested voltages anywhere yet, as I don’t know exactly what I’m looking for. I have not combed over resistor values yet, as my brain needs a break from it, so thought I’d bring it here in the meantime. I have tested with two different power supplies, both of which produce the same result, and both are known to be good supplies.

Head to the troubleshooting forum. Take plenty of pics and measurements according to the top few sticky threads. We'll sort it out.

Thanx, but I literally changed everything in the Octaclave. Flipped the transformer around twice. Even tried silicon diodes. Still won’t make a peep. I probably won’t use it much anyway. I’m tired of messing with it. I’ll use the jacks and knobs on a different build. Glad I didn’t drill out the enclosure yet.
