I've been asked to do some street playing (busking) for the summer and it would be fun. My issue I don't own any amps that run on batteries. The guitarist and drummer have done this before so they are all set. I do not want to get involved with car batteries and power inverters. It's just too much stuff to have to haul out to the street and hook up. I want a battery powered amplifier, preferably rechargeable. 25 watts would be sufficient. I am planning to disconnect any internal speakers and hook up a larger cabinet in order to get more volume. The battery has to last 3-4 hours. I realize I may be looking for something that does not exist. -- I've read conflicting reports about the Pignose Hog 30's actual wattage and I cannot audition one locally. The price is right, though. -- The Phil Jones Briefcase is just too expensive. -- I've seen a few battery powered PA systems, some up to 100 watts...again I cannot audition any locally. I'm interested in finding out what other street players are actually using.
