I'm a former professional musician and take great care of my gear. ***Comes with power supply*** Line 6's PODxt is a two-in-one: it's an amp emulator, packing 32 amp models into its small housing, and it's a multi-effects pedal, boasting 35 classic stompbox and studio effects. The PODxt comes with 64 presets, tap tempo functionality, and a chromatic tuner, just to up the ante. USB I/O allows direct recording to your DAW and the potential to download more effects into your PODxt, and its MIDI capabilities make it super versatile.
