Probably because I don't think it's a standard model. I'm no expert, but it appears to be a modified or custom Yamaha bbg4. It's got the body and pickups of the bbg4, but different headstock (4 in a row vs. 2+2) and different electronics (either active or individual volume and tone controls for each pickup). Also, that's a custom color or refin for sure.
Given Mr. Lee's stature, I imagine he could easily ask Yamaha to make him whatever the heck he wants. I would be interested to know why he used it and not his Sadowsky sig bass.
