Used XSONIC XTONE Pro Smart Stomp. This floor unit combines a USB audio interface with six MIDI footswitches, so you can plug in your guitar or bass and switch presets or toggle effects in compatible amp and effects software while you play.

It has a mic input with 48V phantom power, MIDI In and Out, an expression pedal input, and a headphone jack. Use it for recording at home or controlling a software-based rig live.
