I'm looking for a small amp to take to open mics so that I can play with my guitarist buddy (usually acoustic, occasionally electric). No drums. I normally play 5 strings, so I'm trying to find the right balance between portability and frequency response. Granted, I don't hit a low B very often. I don't have ready access to the Phil Jones so I can't test drive it. The Ampeg sounds OK but is a bit chunky and I can't get freq response info. Fender Rumbles left me underwhelmed. Opinions? Go!
