Ok, i'm now ready to step up from the combos to the real rig. I was hoping somebody can explain the amps to me. Like, what are ohms? How do you know what head is compatible with what Cabinet? If you head is 50 watts and your cabinet is 400 watts, do you only get 50 watts when you play? I know your hook your head up to your cabinet, so what are Preamps, Poweramps, and Stacks? I'm new to all this stuff guys, so take it easy on me.
