I've liked the new Fender acoustic amps, but am currently using a pair of 50 watt Yorkville powered monitors, designed for P.A. use. They are much more "hi-fi" than an electric guitar amp. They also double well as regular monitors and can be "daisy-chained". They don't have enough tone control but my outboard system supplies enough. They also accept a mic cord directly, as well as a 1/4 inch phono plug. As they have two angle positions, they are easily set up so I can hear and/or be heard. For small gigs, they are sometimes all that's needed, sans P.A.My only regret with these are that I didn't get the 100 watt version, because once in a while I need to amplify others as well. Btw, I even play electric bass through them sometimes.
Other ideas?
Peace, Mooh.
