I'm looking for a good sounding practice amp. Something warm sounding without alot of coloration. This amp will never leave my practice room, except for maybe an occasional patio or garage Jam Session with friends. I am looking at the Ampeg BA112... I would love a B100R or B50R which receive a lot of praise on TB. But, there aren't too many of those to found for sale and when I find one they come with comparatively higher prices naturally, and always seem to be found fairly distant, so combined with shipping cost make them out of the price range I'm wanting to pay for a practice amp. Is there any differences (pro and con) between the newer and older models of the BA112? I see one at 75w and the other at 50w, but other that that, what? Are there other amps in the same price range to consider that sound as good or better? Any advice from knowledgeable users will be appreciated.
