My whole mentality is centered around the 10 years I spent in working bands. If a piece of gear won't work in that context, I won't own it. I have said on here before that you will never catch me playing live anywhere with less than a 50W amp, and I have caught a good load of flack for it, but the flack makes no difference, I have my reasons and they are sound. Until you have spent a good number of years on the road playing every kind of venue imaginable, including a good number of sh*thole bars with acoustics that soak up sound like a sponge, you just won't understand. I not only have a BelAir, I also have a matching 2X12 cabinet for it. Why? So that in some craphole venue like that, where the bass player on the other side of the stage can't even hear me, I can place that cabinet over on his side of the stage. In small gigs, well, as far as I'm concerned, if there isn't room for another 12" of floor space, it isn't a gig or a sports bar, it's a closet.
I have quit tube amps entirely however. I currently use a Fender Mustang III and will soon be getting a Quilter MicroPro head ahd HD 1X12 cabinet. One big reason for that switch is that the Quilter can handle just about any speaker load you plug it into, and I can then still use that Carvin 2X12 cabinet if need be.
