A friend of mine is thinking of getting out with his guitar and the singer in his band to do a little busking, and have fun while (hopefully) collecting a little cash. I was asked to join in on bass... the trouble is I can bring a 450W amp (well, maybe now), my 45W practice amp (hmm, still needs to be plugged in), or nothing. I don't like acoustic basses. They do not work acoustically. They may sound nice, you may like that sound, but they're far too quiet to be any use busking. So I am thinking of an amp that can run off batteries and I'll bring that and one of my electrics. I have found the Roland Bass Microcube RX. Seems about right. A bit more expensive than I'd like, but if it works I'd buy it. But, does it work? The guitar version is great, but I feel this may be a bit underpowered and I would fel very silly carrying the amp to not b heard in teh end... for that I can borrow an acoustic bass guitar! I was looking today in a few shops around and they don't have it, so I can't try it for myself. I'll keep looking, but I was wondering if anybody here has experience of this amp, or other amps that can work for my purposes. Any comments/ideas?
