Can you use the GT10 as a recording interface for a mic such as the SM57? How does it compare to something like the M Audio MobilePre interface?

Epiphone Les Paul Standard
Fender MIM Standard Strat
Fender Deluxe Reverb
Digitech Bad Monkey
Electro Harmonix Big Muff
Ernie Ball VP Junior 250k
Dunlop Cry Baby Wah
Ive never worked with the GT8 or 10 yet but I would think it would mostly record the guitar best. For mics, I would tend to go with the m-audio interface....simply because it has proper XLR inputs and most likley, better preamps.
