I can pipe in with what doesn't work well...Rivera Fifty-Five Twelve, Guild 66-J, Guild 99-J...Laney VC30 almost works...electric guitar amps just don't cut it for acoustic...there is a big Genz Benz acoustic amp in a certain local guitar factory's office that sounded fabulous with my new D-55...but apparently thats the only place that it does, LOL!
Strong recommendation from a good friend and reliable source that the Fender (shudder!) Acoustisonic 150 is THE acoustic amp to have, and after looking at the spec that is probably very true. Couple 8" speakers, high freq horn, digital amplifier (also in the Acoustisonic 100, but NOT in the others in the series). Yeah it does a lot and is big, but not heavy at all...the 100 is even lighter, but doesn't look like a cool old Vibroverb. And then of course there is the other source, Doyle Dykes sounds pretty good through one!
I understand completely about wanting to play with some effects at home, its fun! Sadly, even a Aphex Acoustic Aural Exciter pedal can't make an electric guitar amp sound like an acoustic amp...ask me how I know...
