Just curious here, but I seem to like the tone of non-master volume amps better than if I used the master volume on an amp. It just seems to me that cranking the preamp tubes with the master volume makes for fuzzy and farty distortion. Does anyone else experience this? It just seems that turning the master all the way up and using the gain/volume as the actual amps volume knob sounds best. Can fuzzy preamp distortion be fixed with tubes?
