I've never played a solid state amp that I've actually liked, and I've played out through a lot of rig combinations in the short amount of time I've been trying out gear. Sure, I can get 'my' sound out of it, but it's much harder to dial in for me, and I always feel like I sound glassy and way too up front... kind of like ear buds vs open ear headphones. To me, it's like trying to get a Strat to sound fat when what you want is Les Paul tone. Of course you can do it, it's just gonna be different.
In all fairness, though, I've heard some other bassists get great tone out of solid state amps who swear that they can't get a tube amp to deliver their sound. And I believe them. There is no one stop, end all gear setup that makes every player sound good. Tone is a sum of all the parts, and at the end of the day it's all subjective anyway.
As for me, I'll stick to my V-4B.
