Fender '57 Bandmaster Reissue - Bright preset

Verified · 93/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The '57 Bandmaster reissue recreates Fender's narrow-panel tweed Bandmaster, a 3×10 combo based on the 5E7 circuit. Mic and Instrument channels each have two inputs and their own volume, feeding shared treble, bass and presence controls. A long-tail phase inverter with negative feedback drives a fixed-bias pair of 6L6GCs from a 5AR4 rectifier, rated 26 W RMS. It gives an open, airy clean tone that breaks up into tweed grind as the volumes come up.
