I apologize for yet another "best portable rig", I realize it has been done several times. It seems people often come back to Eden, Aguilar, Epifani, Bergantino and EA, to name a few. I've been searching the archives and there is a lot (too much) information so I'd like to narrow the question down a bit... Please help me with some examples of small rigs (can be combo or amp+separate cab(s)) that can handle a low B. "Decent volume" means blues/rock rehearsal without PA support. Other use is not so loud monitoring on stage. I would choose good sound rather than loud volume. It must also do a decent job amplifying an electric upright. Music style is varied, from electric blues and rock to upright jazz. Cost should not be limiting the options to start with. What I'm aiming for is a maximum of let's say a pair of 1x12s or similar size cabinets if possible, I don't want to carry any 4x10s anymore.
