I'm about to pick one up to use as a practice amp so I can leave my tube rig at the rehearsal space. I know there has been lot's of threads about the ZT stuff already but they've still left me undecided. How is the headphone/direct out sound? Is there any cabinet emulation going on in there? Can it really handle keys well? It would be handy to have for a keyboard amp to leave the P.A just for vocals for small gigs. If I was to run a digital tanpura or some kind of backing into the aux in would it sound ok for live? Or is it more for practice purposes? Maybe I'm expecting too much out of the amp but it seems like it could be a versatile little tool to have handy. It would be nice to hear from anyone who owns the Club or lunchbox for that matter.
