Well 3 if you count my Ampeg Rocketbass RB-110 that I practice with. But my 2 gigging rigs (raucous blues band) are an Ampeg PF-50T that I can pair with either 1 or 2 PF-115HE 1x15 cabs. So it's usually this with 1 PF-115HE for small gigs/rehearsals, 2 PF-115HE's for up to medium stages with FOH support. 2nd is the Bassman 100T with the Bassman 410Neo 4x10 cab, which easily handles up to festival-sized stages. Both are all-tube with the Ampeg @ 50 watts, the Basman @ 100 or 25 watts. The Bassman @ 25 watts sounds fantastic for small up to medium-ish stages, but it is a load to mess with for small gigs. What I haven't tried is pairing the Bassman with the Ampeg cabs and vice-versa, they're so well matched as is it hasn't really occurred to me.
As a bonus both of the heads have post-output transformer (post-power tubes and transformer) DI's that get the full tube amp vibe to FOH without having to mic the rig.
