Yep. For use at home and during low-volume rehearsals, or even a supper-club gig, the Baby Blue should work fine as a standalone amp.
On the plus side they have flexible EQ that mates well with Alembic basses, are easy to move around, and boom well when paired with a good extension cabinet.
On the minus side, the EQ controls' design makes it impossible to boost both lows and low-mids at the same time, meaning fretless basses disappear in the mix, and those 8 speakers don't throw low frequencies AT ALL. Also, though the BB was billed as an excellent recording amp, the one time I tried to use it for that purpose the results were disappointing to say the least. It left the ranch within days. Not to say I don't miss it from time to time, though...
