I'd say I'm pretty typical. At least for someone in the rock/metal scene.I didn't say never. Do you think you're out of the ordinary or not?
A lot of players I know only have one bass amp. Some have more, but often they run them together (this is usually the case with the louder doom/stoner bands).
Most of the players I know are 20s-40s. For most of us, weight doesn't seem to be that big a deal. I think Talkbass can often give people a skewed sense of how much weight matters due to the user base being, on average, significantly older than just the average gigging musician. Lots of people in my scene are in bands where we all help each other move gear, as opposed to hired guns who only move their own gear. So little distinction is made between heavy guitar amps versus heavy bass amps. They're all just "our amps." While not all guitarists use high powered amps and 4x12 cabs, guitar combos are still pretty hefty. So the weight of my particular amp is not that significant in the grand scheme of things, compared to the sum total of the band's gear.
Personally, I'm happy enough with my amp that the only thing that would replace it would be another tube amp. I've tried a lot of the newer Class D heads out of curiosity, but they all leave me unsatisfied.
