I use one of these all the time.
This is a great little amp for coffee shop gigs, where you need a little PA, for just one mic and guitar with a pickup.
I just used ours for a memorial service just this afternoon. It easily covered the whole room, 60-75 people, and I didn't even have it turned up much.
I usually use it every week to play at church as a stage amp for just the acoustic guitar. I take a line out of the effects loop in back, into a Behringer direct box for the PA. I have an FX pedal patched into the Instrument insert in back, as well as the footswitch (I use the Chorus a lot.)
