This is actually a really good modeler. Ive had the pedalboard version as well as the head and combo version and they all sound great. Id say these units are my favorite modeler in terms of tone. Im not sure why they put the USB on the pedal version, that doesnt make much sense but this does have MIDI and S/P Dif Out. It has a separate setting for line/amp depending on how you want to use it and my favorite feature is the headphone out for silent playing. It's stereo too and comes with a power cord. May be interested in trades for other music gear. I'm mainly interested in in Strat/Tele/PRS +/- cash. Check out my other postings too.
