Amp for upright bass

[JBarz]

Acoustic Image Contra Combo for 20+ years, but it is now beyond repair.

Is the cabinet or the amp beyond repair? I had a AI combo crap out this year (rattling), but the amp came out with a little finesse and pairs brilliantly with an Acme or Barefaced cab.

do people still use Walter woods amps?

I do; proudly!

If you had about $500 USD and were looking for a small combo for practice, small gigs, etc, what are you going with?

Used GK or PJB combo? Mark Bass back line 1x12? What’s your pick?

I think you’re forgetting that the OP had
a combo amp and is looking for another
combo amp.
What speaker are you recommending
to use with the AI head? This seems
to be getting rather expensive and doesn’t have the convenience of a
combo configuration.

I like the BG400 combo because it's one of the few combos still in production for doublers.

That being said, you might be able to figure out how to get a Mark 1x12 combo, swap out the head for a Mark Tube 800 (as it has 2 inputs), sell the original combo head to recoup some of the cost (or keep it), and use that to double. Just a thought.
