see those two funny looking things on the side of your head? kind of oblong, has a hole in the middle? those are called "ears." funny thing about them...they work way better to get a sound than idiot lights on your amp. use them.How hard can I hit the gain control, I've got it at about 10past. and just brought the master down a bit. Now if I need some more am I ok to turn up the gain more, what is the optimum gauge?
