Flax,
I use an Ampeg BA-115 for a small amp, and it works fine. It has a direct out, plus it has a headphone jack and two plugs so you can plug in a CD player. Single 15 with horn, and I've used it on smaller gigs. 100 watts, so it won't be too loud. Ampeg also makes other small combos with tuners, etc., so you might want to check them out. It's not tube, so you won't have that warmth, but it sounds pretty good to me. As I recall, mine cost about $400 brand new, so it's actually quite a bargain.
Besides, anything sounds good when an Alembic is plugged into it! I know that for a fact. Last night I went to an open mike night here in Fayetteville, and played my Europa through a Fender BXR (hope I got that right) combo, with one 15. All the other bass players kept asking me what I was doing to make it sound so good. Had to tell them, dial 1-800-Ale-mbic, and you too will have this sound!
Best of luck,
Alan
