I've only used Marshall bass amps. ....1..when I had an old all tube Super Bass 100w amp. ..was nice but limited
Once or twice I've used a solid state combo - probably back in the 90's. ... I think it/they were "Bass state" series amps... they were ok. ..did the job at the time. I think they were made in UK and were pretty decent quality. .. and did what they were supposed to do.
I'd be wanting to get it very cheap as it most likely wouldn't be lightweight or easy to move.
If it was in good mechanical condition it'd probably be a solid unit.
