I'm looking for a $100 (approx) practice amp to get some decent jazz tone from. I've read about Crate, Kustom, Vox, Roland, Peavey. The choices with a 12" speaker appeal to me as I figure that they could put out the lows needed. A 5" speaker probably won't cut it. A beefy 8" might. Reverb would be nice but the modeling features that alot of these small amps have don't really interest me but I could be persuaded. Any recommendations?
