I bought a Blackstar Fly for quiet guitar practice and its usable with a bass, so I imagine the bass-specific version is very good.
My 'proper' bass practice amp is an Orange Crush 25, which has a 'pad' button that keeps things sane. Actually had a (very civilised) jam last week and I left it on the pad and barely went over 1/4 on the volume, I reckon you could do an 'unplugged' gig with it or even a small pub. Downside is no DI ou,. Advantage is that any and all basses sound fantastic through it, disadvantage is that it seems to impose the 'orange' sound so if you are 'Mr Trace Elliot' it may not be your cup of tea.
