Out of pure boredom and as a small hobby, I want to start producing songs on my MacBook Pro, but the built-in microphone is nowhere near powerful enough to pick up my two Fenders (guitar and bass). There's really no point in having an electric guitar if it's not amplified, so I'm looking for a small, desk-top way to do that. I'd like to plug into the mic port and record with GarageBand, but obviously there's the matter of amplifying the signal from the guitar to the computer. I used to use a cheap Altoids pocket amp from ThinkGeek, but that has since crapped out on me. I'm looking for something less jerry-rigged and more permanent. Small and inexpensive are the keywords. Any suggestions or recommendations are greatly appreciated.
