Don't have much to offer, but the build doc says this is a potential problem:
Have you checked against DeadEndFX's build doc? I'm in the process of building their version, but don't have it done to offer comparison yet.
If anyone's built any DeadEndFX builds, y'all've seen the printing template is really just the PCB with (most of) the drilling placements, but does not match any external dimensions of enclosures. Also there are no placements for power or jacks- and there are often many. Nor are there footswitch...
I have 3 I'm building side by side, exact parts. Waiting on the 3207s to show up, but can share notes when they're done in 1-2 weeks, figure that'd be a fair comparison to see what is or isn't simply part of the circuit's sound.
