I use my Ampeg 810 in every situation.
If it amuses you to lug a fridge everywhere you go, you can physically handle it, you love that sound, and you only play gigs where that porker actually makes sense, then more power to you!
In 1973, I was 17 years old. I was on a trio gig with a 50 year old jazz drummer who mostly used brushes, and another old guy who played a Farfisa organ through a 12 watt Gibson Minuteman combo (!!!). It was a small wedding reception, with maybe 40 people in the room.
I had a decent 1*15 combo loaded with a JBL 15 at home. It would have been perfect for the gig, but I had just gotten a Gibson Les Paul bass amp. It featured a massively oversized 2x15 cab, with a 200 watt solid-state power amp mounted in the bottom of it. I took my new baby because I wanted to show it off, and of course I never got it off idle all night.
At the end of the gig, a drunk pushed past me as I was carrying the cab down a rickety steel fire escape. The resultant fall was the cause of a lifetime of chronic back trouble, and the reason that I now have to consider weight in every musical purchase I make.
Funny thing when I look back on those days:
- 17 year old me still wishes he hadn't felt the need to show off. We played polkas most of the night, and there he was on a tiny little stage with a cab large enough to sleep in!
- 25 year old me was always slightly relieved to see an SVT stack at backline gigs, because it meant that I wouldn't have to worry about being loud enough. However, he never cared for that tone.
- 65-year-old me has been playing 5-string basses for about 35 years now, and I am tremendously grateful to companies like G-K, SWR, Eden, Bergantino, and AudioKinesis. Thanks to their innovations, I have been able to make the tones I always heard in my head a reality, and to do it without needing a support crew to carry my stuff.
