OK. Since I started coming here i've learned about 5X as much as I knew about basses before. I think I should learn a little bit about amps now. Can Someone explain what each amp does for what? I know Combo's (of course, simple) but the rest I haven't learned much about. From what I think I know, you need a Head and a Cab. What exactly does each do? Is there any limits on one that limits what you should get for the other? Any good combiniations of wattage? Should one have a higher watt output than the other? Sorry for being such a newb But I think it'd probably be worthwile to know this stuff before I make any rash descisions. Thanks, and sorry if this has been posted somewhere.
