I dont know what a master volume amp would have to do with an amp's available headroom. All a master volume does is attenuate the signal before it huts the power section. With it full up its essentially out of the circuit.
Well, you know a little more (read:a shit ton) than I do about amps. In my life of playing guitar I've pretty much always used master volume amps using the two volume knobs in relationship with each other to determine the ideal volume and saturation. I can usually get a clean signal to go louder, by only adjusting the master volume, but the few times I've toyed with an old bassman or something when it starts overdriving, then that's just it.
Isn't the input volume attenuating the signal hitting the preamp section, and buying me headroom? Or am I perhaps using the term 'master volume amp' all wrong?
I say this not as an argument, but in genuine curiosity.
