There is a *lot* more gain on the channel, plus IIUC the EQ is
modified so that the highs and mids are a lot stronger than the lows.
I think the idea is to use both channels at the same time when you are
soloing and just channel two all the rest of the time. I'm going to
put a jumper on the circuit board so that I can switch the extra gain
stages in and out. I'm curious to hear what the tonal mods will sound
like by themselves...
