I'm looking into making my rig useable for both synth and bass. Currently I'm running a Peavey Classic 400 into an 810 and an Ampeg V4 into an Ampeg V2 412 with upgraded speakers, in a doomy project. Volume and low end are very crucial, but I'm mainly playing bass vi and keys/noise. I'm considering picking up 2 of the Carvin LS1503's that were really popular here a couple of years back and running them with a Fender PA 100 or similar. What other suggestions do you guys have? Obviously I'll run through the PA live for the most part, but we play a lot of house shows and smaller venues where PA support isn't adequate.
