check your hotmail,theres a schematic with the midboost. Yes I use the mid-boost on
my 1200s. kinda like a lead channel switch,
really cuts thru. Haven't really studied the
contour circuit,however to my ears it seems
to control the effectiveness and rolloff points of the tone controls. I really don't
play a whole lot with the tone knobs.This
amp is pretty much a loud ballsy,peel the paint,clean,chunky rock and roll machine
that does a real sweet surf too. And thats
through my 4-10 Cab, with a full stack of 12's its downright painfull.
