I don't gig right now, but I used to and will again soon, so my rig is justified, methinks.
I always used to play on a Peavey Combo 300, well under par for the gigs I did later on owning that sucker, but in the bedroom it was just fine.
I switched to a GK backline 600 with the 210 and 115 cabs, also under par at gigs, but massive at home.
Now it's a Carvin R1000 with the same cabs. I always use an Ibby SR506, and I'm working on what may or may not be a 50's Rhythmline P-Bass right now.
