​The Model H is the beefiest BearFoot yet - sort of an amp like overdrive with dynamic distortion abilities. At its tamest it is Pete at Leeds, all about dynamics and handpressure dirt --- and up from there it just gets richer and growlier and the whole range is useful. Pissed off HiWatt is the homage thats paid here. The first third of the H drive knob is were the actual Hiwatt feel flavor resides - past that is all gloriously grinding gravy ~~~ what if a Hiwatt went to 11 or 20 or ??? Very cool ! The middle knob is not a treble roll off like most tone controls... it has that effect, but it also changes the head room and 'impact' ~ its more like moving the mic in front of the cabinet which is really useful when recording or stage micing ..... Can be safely run at 8 ~ 12v.
