Hi Myles,
Heres a quick one for you:
Two cases:
1) I run my preamp master at 10 and clean valve poweramp (Marshall 20/20) at 1.
2) I run my the preamp master on 1 and clean valve poweramp (Marshall 20/20) on 10.
The question is, if the perceived volume is the same in both cases, will I get a better tone due to poweramp valve compression in case 2?
Appreciate for your time.
