Here's a picture of the Thumb in question.
I first thought I wouldn't like the tone with the way the pickups are voiced, but now I see that it sounds awesome in the mix. And it's very easy to play. I know it's supposed to have neck dive, but I haven't noticed any. That may be because that Levy's strap came with it, and the leather on it grabs my shirt pretty well. In any case, it hasn't been a problem.
I'll be gigging with it for the first time tomorrow night. Can't wait!
