Just got it last week, looking forward to using GarageBand as I love playing guitar (electric especially). Unfortunately, I have zero clue how to plug in my guitar to my laptop, and have no idea what cords or cables I need to do this.
If someone could help me out, I would greatly appreciate it. Thanks!
There is a USB to 1/4" phono plug that you can use. I can't remember who makes them though. It's best to get an external audio/midi interface with (IMHO) a Firewire connection. Check out Edirol, M-Audio, EMU, Tapco, Apogee, Alesis io... it all depends on what you want to spend.
