I'm planning to buy a Peavey Valve King 1x12 by summer's end and I hear the distortion isn't br00t4l but it's still pretty good. Right now I have a ss Peavey Audition( don't know the number) and it has a pre-amp out. What does that do, since I really want to believe that I can use for a gain boost on the Valve King and it would give me the best of both amps. Can anyone explain what the pre-amp out is for? Thanks to all.
