You need to boost the signal of a guitar. A compressor tends to
give a guitar more sustain, which is nice in this patch. I 
was using a Chandler Tube Driver, which can also increase sustain.

Yes. The output of a guitar is in millivolts. MOTM wants to
see something more like 10 volts peak to peak. However, in the
case of the 700, we only enough voltage to swing the comparator
so a line level signal is strong enough.
