My new Ampeg V4B and SVT 212 AV. My first Ampeg and only second tube amp since 1975. Swore I'd never sell my Shuttle 6.2 combo, then I played one of these at GC and the GAS overtook my senses. This is the sound I've been hearing in my head. Bass is a Fender Select P with GHS Precision Flats. I think I shut off the lights and play by the warm tube light.
