I've been using a Palmer Pocket Amp Bass, for a couple of years. Either DI into the console, or split into my backline amp. My band also uses an LD Systems Curv PS for smaller gigs, so when my backline amp came up for replacement, I thought of using a full range powered cab instead of a traditional back line amp, and naturally looked to LD to provide it. I'm very pleased with the performance for bass guitar. On occasion, I've also used it as a PA system for "unplugged" gigs, it easily outperforms the JBL systems that we were using previously. At 20 Kilos, it's much heavier than most similar alternatives, but it's worth it for the tremendous performance advantage.
