I use this DI on live performance using an AKAI EWI USB: computer>audio card>volume pedal>ART DI>PA. It sounds fantastic. It has ground lift and a very clean and robust output signal. There is one drawback. The on/off switch is right next to a large bolt that keeps the battery latch closed. The bolt was very tight and I couldn't remove it by hand. Using a pair of pliers, I broke the switch. Not the internal switch, just the clear plastic push piece. It still works fine, but it would be better if they could put that bolt somewhere further away from the on/off switch.
