OK disregard cub8,
how about
Vox Pathfinder 10 or Fender Bullet Reverb or Fender front man.
same usage as I indicate
Go for the 15-watt version.. Vox Pathfinder 15R..
Tried it for electric, acoustic, microphone, mp3 player, and sound system pag gusto mag movie marathon sa gabi... it works nice and is plenty loud.
I have not had much luck with a tube amp + acoustic guitar.. it just doesn't sound right.. Tried it on my '1974 Fender DSR, H&K Statesman, Peavey Classic 30 (horrible sound w/ and acoustic guitar), and my brother's Blackstar HT20..
