I got an old Peavey Artist VT a while back that I really like. I've just been playing around with running my pedal board into the Power Amp In and am enjoying the sound with my board. It seems that running into the Power Amp In without anything going into the Preamp bypasses even the Master Volume and the effects board becomes the only level hitting the fully open Power Amp section. Is that correct? Any idea on these amps what impedance would be "best" to hit the Power Amp In with? I'm thinking in terms of if my last pedal should be one with lots of gain or I should try a mic-preamp w/ built-in DI and unbalanced out or. . . Also, of course, am I screwing something up? Below is the relevant section of the manual that is difficult for me to understand given the way that I'm bypassing the Preamp entirely. Any advice is greatly appreciated!
