almost a perfect build and almost no issues 😉  my volume pot behavior is reversed.  otherwise, this is a super nice-sounding … overdrive? pseudo-cab? distortion? .. it does a whole lot depending on volume before and after the gain stage.  after playing around with it, it will go at the end of my gain pedals.  I added a clipping option between some germaniums and led.  both sound killer with subtle differences.  i have a lingering issue with a stripped power jack nut – my fault and correctable, and I’ll overcome the pot issue.  thanks all for the contributions to this and other forums!
