I'm starting to play again after taking a decade or so off. I live in a small apartment in Taiwan, and while I'd love to have a stack of speakers and rock out, it's not in the cards right now. I would like to mess around with Garage Band on my Mac and start playing bass through the computer. The thing is, I haven't done anything with gear since Clinton was president and have no idea where to begin hooking a bass up to a computer. Someone told me I could do this with a preamp? I'm not looking for a top of the line professional rig, but I don't want crap either. Any advice?
