Dunno really, I’m currently very happy with my basses - all 3 are ‘bitsa’ builds, and I’ve built them to meet my own playing needs, so I guess I’m alright for basses.
It’s be great to play through an old B-15, so I’d probably buy one of those (not technically new though, so I’m not sure it that counts).
Failing that I’d go with an Ampeg 6x10 and an SVT Classic head.
On an unrelated note I’d probably get a new sofa too.
