The first amps Marshall built were built from a 1959 Fender bassman schematic. The biggest difference was they were built with British components rather than American parts, so they had a unique sound. IIRC , they used 12ax7 tubes in the preamp instead of 12at7s . The 12ax7 is a hotter tube, so that coupled with the lower headroom in the British Drake transformers gave it a dirty growl when you wound up the volume a bit. Coupled to the old Celestion greenback speakers, the sound of a legend was born.
