hey, I don't know much about amps, so forgive me if this is a stupid question. I have a Fender Bassman 60 amp and it has 2 little lights labeled "pre amp clip" and "pwr amp clip." It also has a button labeled "limiter." What exactly do the lights indicate when they blink? What does a limiter do? I just figured it has something to do with protecting the amp, so I always have it on when jamming. Is it bad to crank the volume all the way up? I'm really paranoid of damaging my rig. How important is it to have a big amp? Almost every gig i've played I've mic-ed my amp and run through the venue's PA (or whatever it's called). Is that bad?
