Fender Cbs 45W Mstrvol Pullsw Super Pro Bmstr preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

This CBS-era schematic covers the 45-watt master volume configuration shared by the Super Reverb, Pro Reverb, and Bandmaster Reverb from the mid-1970s. The addition of a master volume control and pull-switch boost represented Fender's response to players who needed stage-volume control without full power — a significant departure from the original fixed-volume philosophy of the blackface era. Pull-boost switches on some units could push the preamp further into crunch territory.
