Greetings, Well I was struck by PeteB's thread https://www.tdpri.com/threads/saturation.1080711/ But my question is substantially different, so another thread about saturation. I have Marshalls, all with master volumes. I quite enjoy the preamp distortion brought on by overdriving some (or all) of the (6) 12AX7s in the preamp. I have never taken one out into the countryside and dimed it so I don't know how much (different, better) it is than what I know. I guess I'm going to listen to the little 1 watt on the top and listen to what it does. Who wants to take a stab at describing the tonal differences, perhaps with examples? Thnks .. . . .
