They didn't sell well when they were new, since Gibson didn't market them very well and they didn't find their players right away. Gibson did what Gibson does and quit making them when they started to get discovered.
Funny thing about mine. When they first came out, I was unimpressed. As a long time player of Gibson bass guitars, I tried one, but didn't think that much about it. This is TB, so there's always another bass to buy, and when a used one popped up, I went for it just to see what it was like. I bought it from a guy who said he had moved on and only was playing fivers when it was a year old. I got it for $500, shipped, and with the case. It was in mostly perfect condition, except there were marks on the neck where he had written the E-string notes on the side of the neck with sharpie. I thought that was pretty funny. Those notations are all worn off now. A couple years later, my brother, who is a dedicated Fender Jazz player, tried it and completely fell in love with what it could do. I wasn't playing it all that much, so I sold it to him for $500 with the one string attached that if he ever wanted to sell, I could buy it back. About a year later, he had decided that he didn't love it at all and sold it back to me. It won't be going anywhere now.
The only things I didn't like about it were the upper strap button placement and the tort pickguard. I like the strap button at the heel of the neck, since it can balance a lot of different ways when the button is there instead of the upper horn. I guess that's a Gibson bass player thing. And the tort pickguard has been replaced by a black one. Tort pickguards just don't belong on Gibson electric guitars or basses.
The matte finish has burnished over the years to a soft glow that's not exactly matte, not exactly gloss. I really should play it more.
