I finished building the Triangulum Boost this weekend and I'm noticing an issue that I'm hoping someone may be able to provide some clues as to what may be going wrong. It's working for the most part in that it turns on and the one knob works as expected. The issue I'm hearing is that when the boost is increased it gets to a point where this really high frequency noise is introduced. I tried recording it but I haven't been able to capture it very well at all and it's also hard to explain in words. It's almost like a high frequency "rattle" that is introduced after a note. Easiest example would be if I were to just palm mute an open E; the palm muted note would be heard and then afterwards there's a trailing high frequency noise. It's like a ping or rattle, almost as if my cab were shaking, but it's not as I've never heard this kind of noise come out of it with any other sort of boost pedal.
In case it helps I'm using a JCM800 with a 4x12 to test it out.
