I was wondering what I'd have to do to record with a pedal using a USB interface. Do most USB interfaces have a port for it or would you have to pay a lot for one with it? I haven't seen it on too many. I know Guitar Rig is built for that, but it's too much money.

I was considering getting the Presonus firebox, but changed my mind and think if I got a $100 interface and a $100 Digitech whammy pedal I'd be better off. Also if anyone could suggest a good $100 interface that'd be helpful. I was looking at the M-Audio Mobile Pre, but I think they recently ran it up $50 so I guess my next option is the M-Audio Fast Track.
There be no shelter here.
