Depending on the gig, I've been using a Peavey PA (600 Series), with either 2 Cerwin Vega 15" speaker cabinets or 2 off-brand 12" speaker cabinets (plus a small powered spot monitor). Sometimes, in an attempt to conserve setup space and have less pieces to connect I've been using my Peavey KB300 (a heavy amp). Since my one-person-band brings with it the one-person carry in, setup, tear down, carry out, I'm looking for a good compromise of weight, size, complexity, and sound quality. Any ideas?
