Greetings,
A few years ago a repair tech showed me a "trick" he used on Fender Blackface amps...he disconnected a capacitor or resistor or something...from the back of one of the potentiometers (I think it was the Bass pot) with the result being a massive increase in volume from the Normal Channel. A couple of years ago a repair tech re-soldered the connection to bring the amp back to factory setup.
Does anyone know what the first tech might have disconnected? It was a simple, one connection he unsoldered and left the lead from the component attached. Neither tech is currently available for consultation.

Many thanks in advance,

RB3988

What you are talking about working on a potentiometer look this mod ;
Simply unsolder either lead of the resistor to the left lug of Bass pot

Read page 155 , read left par.
