I owned one for over three years now and, Yes!!!, Iv'e used to perform live. We mic'd it through the sound system and did the SRV set. Use a single coil guitar (or coil tap switch) and the G-Dec's "Black Cat" or "Bad Boys" channel and you have a sound very close to an SRV sound. It's not perfect but the folks in the club seemed to enjoy it.

Enjoy ...
