We use a Roland Cube Street for the guitar and vocal mics, and a Crate Taxi Limo (with a mod - 8" Eminence bass speaker)for the bass and backing tracks. Total wattage - 55. Sounds pretty good.

If we can get power, we bring real amps.

For just a guitar, mic and tracks, I would look at the new Cube Street. Of course, it came out just after we bought ours! mad

The Roland effects sound great, and the little bugger is wicked loud! grin
