This is going to sound really weird, but I recently acquired a fairly new Behringer PMX2000 powered mixer. It is a 10 channel mixer/PA that goes for USD$300 new, and puts out over 200 watts/channel. I hooked it up to a 4 ohm Carvin 2x10. Using just one output channel (half of the available power), the results blew me away - huge sound, totally kicks ass! The group consisted of three guitars, keyboards, and a loud drummer playing rock/funk. My bass is a Pedulla Rapture. We also ran two microphones through the PA. Now get this - my normal rig is an Alembic F1-X and a QSC PLX 3002! I'm telling you, this PA is 95% as good as the Alembic/QSC for bass. Very portable too.
