i might be buying a 12" 867Mhz Powerbook G4, and i will want to be able to use it for garageband, i know the system itself is perfectly capable of running it, however i have a bass guitar that i would like to be able to record music with on the powerbook, my questions are these: Can i hook up an electric guitar/bass to this powerbook, and if so what do i need to connect it? thanks a lot!
