screamingdaisy said:Soldano created a preamp design that included a cathode follower when he was modding Marshalls back in the 80's. This circuit evolved into the Soldano SLO. Peavey copied this design for the 5150s, Mesa copied it for the Rectifier, and Marshall copied it with the JCM2000s. So far as I know, just about every other high gain amp (Bogner, Framus, ENGL, ect) has copied the same circuit.
