Not an owner, but I was a Gibson dealer (as well as Fender, Guild, and a lot of others) for 11 years, 1977-1988. I liked the Rippers a lot- well thought out, and nicely made instruments. The Grabber was a cool idea, but didn't really work all that well. The EB-0 wasn't useful for me, and I'm not a fan of the short-scales but I still kinda have a hankering for an EB-3 just because of Jack Bruce...
The Les Paul Triumph bass was a cool thing, but I thought the neck was a bit too much like a toothpick. They were heavy, and the gazillion knobs and switches didn't make it real friendly on stage. But a good friend of mine used one (through an Acoustic 370!!) and Carl sounded great when HE played it.
The best ones? The original Thunderbirds with those unique pickups! They LOOK RAWK 'N' ROLLLLL!!, they sound great, and it's not a Fender. See, that's the thing about Gibson basses- they don't sound like Fenders and that's a good thing, unless you're wanting a Fender sound. Me, I just gravitate towards Fenders more than Gibson's sound so it's Fenders and Fender-inspired basses for me. But whenI I got my first StingRay back in 1979, two of the finest bassist in town and my good friends played it at gigs and we all hung out together talking about. Tom said "it's like the best Gibson sound ever, but it plays like a Fender!"
And don't forget the Victory- the first time Gibson really came up with a Gibson bass that could really appeal to the Fender player. Good hardware, great electronics, and a nice neck- excpet they weighed more than ash Fenders!
There was also the RD series (I swear "RD" stood for "research and development" without any musicians involved...). Expander, compressor, active stuff and a big body. The RD actually was pretty cool, excpet stupd expensive and not enough people who wanted that unique body shape.
As for the EB-2, I find the Guild Starfire, especially the ones with the original Hagstrom PUPs, to be MUCH better basses. But I might be prejudiced, as I find Guilds pretty much always are better isntruments than Gibsons.
