I was playing around with the Kempers distortions and boosters and compared them to my analog pedals. I could get the grean screemer to sound very much like my TS808 reissue and was satisfied so far. But I couldn't get the Treble Booster sounding similar to my BSM RM which is a highly regarded Dallas Range Master clone.
So I wondered what the boosters in the KPA are modelled after? The Lead Booster seems to be a different kind of animal, could that be a HS type of booster?
