Lots of good choices in this thread..I'll add mine..
the old oop Princeton 650..very versatile amp. Good cleans. I use it for fingerpicking my archtops, twanging with a tele and works good with a lap steel. Doesn't have amp modeling, instead it has eq presets as diff settings. Does do dirt well, but shines with clean tones, both dark and smokey or bright and cutting with a twist of a knob. Decent built in tuner, effects are useable (not great, though). I run straight into it a lot using it's built in verbs and delays.
Carried it to a small gathering again this past weekend (played a bunch of Travis picking and Piedmont blues, then switched to steel guitar). Does everything I need with out having to lug a bunch of other stuff. 65 watts with a 12" Celestian is loud enough for me.
