Roland Cube Bass 100 for home practice, rehearsals, and low volume gigs. I could probably play more gigs with it, provided I had good PA support. Great tone, easy portability, durable.
G-K 700RB-II and two Neo112 cabs. I bought this stuff before all the "micro" heads, but this is reasonably portable gear that sounds fantastic for rock with my Fenders and G&L SB-2. I normally need only one cab, which keeps things simple.
I wouldn't mind simplifying further, with a more powerful combo to replace the Roland and cover some single 1x12 cab situations, and one four ohm standalone 2x12 for everything else (like a Genz Benz NeoX 212). I'm planning to take a close look at the new G-K MB neo combos soon.
