Hello. I am new to guitars and using garageband. I would like to hook up my guitar ( SG knockoff ) to garageband. I have been reading this forum ( thanks for the info ) and searching google. I have found connecting isn't easy and you get lots of different answers. I have decided that I want to connect using USB. I think I have decided that the Digitech RP155 would be the best way thats also cheap. I don't want to spend more than $100 - $125 ish. I suck at the guitar so anything more would be a waste, for now anyways. I guess my questions are, would this work as a USB interface and or does anyone here use this model? Thank you.
