I own a Gretsch G5120 and a Gibson SG Classic, and I run 'em through a Monte Allums-modded bluesdriver (or a Rat, depending on the sound I want) into a Bassman 4x10 combo
It's simple, and it gets the job done, and then some.
For acoustic work, I have a Taylor Big Baby, and my bassist has an Epiphone EJ-160E
