I saw someone's formerly gloss black finish done up with this 'stealth' look and tried it myself. Since then I've has a few people ask me how to do it. I thought post that here to help take some of the 'error' out of trial and errror!
This is especially good to use on a guitar with a lot of surface scratches 'cause it will pretty much erase them.

You're just roughing up the clearcoat so you've got to take it easy so you don't go through it to the paint. I wrapped the sandpaper over a small rag to minimize direct pressure from my fingers. Soft foam rubber would work too.
You really should remove the neck and all hardwear.
Start with the back. Keeping the motion even and non directional is the way to get an even finish. Big circles. Almost no pressure needed. When you start focusing on little spots you're going to get into trouble. Be careful around any edges like neck pocket and pickup routes, these will quickly sand down to primer if you aren't careful. Keep a rag handy and wipe off the dust frequently to see how you're doing.
The paste wax will help even things out, and also brings back a bit of dull gloss. You will still need to wipe the bass down, but you'll see your fingerprints as being darker spots rather than dull spots like before. You can maintain it with a scotchbrite pad and wax.
