I want one big time! The slider has a really serious rock tone. Being made entirely of maple it has bags of harmonic warmth, bite and growl. Sort of like a P only better in every way in my opinion. Here's a pic of mine next to my old jazz.

The neck is pretty big, weight is good. Not too heavy but by no means light. It's the only Gibson bass I've ever owned or played so I don't really have a lot of comparison. The pickup in the slider is a master piece IMO, they are also in the explorer bass so I'd love to get my hands on one of those too.
If you weren't so far away I'd come have a go in a heart beat.
