I have Ampeg SVTIII pro head. I was wondering if anyone has had any luck with some of the single 12" cabinets, or a 4x10 cab as stand alone with that Low B of a Jazz Bass. I would like to be able to run it a couple of ways, Ampeg into said cabinet alone. This would be ideal Ampeg into cabinet and 18" cab for big shows (bottom not an issue here) Run as an extension to SWR Workingman's 15 to boost output to 160W from 120W, move more air, and bottom mojo. Seems like some of the single 12s out there are too good to be true. But it's hard to judge a rig till a gig. We are a rock, blues folk band. No marshall stacks or a hero drummer, but we do get fairly loud depending on venue and drink Thanks for your input.
