Can I Use Stage Pre-amp In The Studio?, garage band audio interface needed Options

[lyryck]

Hi,

I'm ready to use my garageband audio recording/editing software, and trying not to spend too much money. I need some kind of audio interface in order to input live vocals. Is it possible to use my existing stage equipment? For example, I have a great little ART tube pre-amp that I thought might work. If I purchased an adapter to go from 1/4" to USB I could plug my vocal mic into the tube pre-amp, and the tube per-amp into the audio-in on my powerbook. Or could I?

Curious.
Am I fated to own an mBox????

Apple sells a $20 Monster cable to get your guitar into the iMac. I can't tell you what it sounds like but for 20 bucks...
