I'm curious about the tone control. Could be that counter-clockwise is a simple hi-pass-to-ground deal like in a guitar, and clockwise is like the mid resistor in a 2-knob stack where the hi-low knob values are fixed. The XLR output is interesting. Celestion speaker too.

If "hand-wired" means point-to-point, these are just begging to be modded a million different ways. If it merely means that they connected the printed circuit board to the transformers by hand.... well then.
I wonder about the low-gain tube. More crunch at lower volume, I guess?
