This may be unrelated to your issue, but I noticed on my PCB (which is MNats Rev J), that the three pads under the distortion trimmer R16 are all connected together. There are three pads just outside the silkscreen part footprint (perpendicular to the three under the silkscreen outline) that appear to be the correct pads. I haven't traced it yet, so that needs to be confirmed.
If that connection was left open, and no feedback applied to the emitter of Q2, you could be running Q2 at far too high gain, and thus distorting all of the devices after.
