Interestingly, no votes for Gibson in the poll. I tried a Gibson Les Paul Standard bass not expecting much of it - I was very, very wrong. Fantastic sound for a great many things. The sound was somewhere between a Jazz and a Musicman (which could be a completely useless description).
I've also previously tried a vintage EB3, Jack Bruce-style, and one of those semi-acoustics a la Jack Cassidy. Big, big sound. Precision-y but rounder and less defined.
Anyway, I don't actually own or play one. Just surprised noone else on here does.
