I've been drummer-less for about a month now. Standing gig every Fri & Sat at a small cafe since Oct of last year, intimate setting, quiet wine bar, jazz, standards, some blues, etc... I've had occasion to do this quite a bit with a few combos, and while I agree it can be fun, I would personally prefer having the drummer, especially if I can pick who it is.
It has improved my timing, and simplified my playing to a degree. I've had to use charts for all the standards I'm not used to, so quite beneficial. I can pull it off when necessary.
Still, I would prefer percussion of some kind.
