Identify this bass?

Hey all,
I got this bass a month or two ago in a trade, and I have no idea what it is! All I know is that it sounds spectacular! Here's some pics:







It's got a pretty nice top, doesn't weigh a whole lot, neck-through, has a nice thick, p-style neck. Duncan Basslines J's and a 3-band preamp, I think it's a Duncan as well. Sounds like a million bucks. Has a few construction inaccuracies, but they are easily overlooked in light of how nice it plays.

Anyone know who I should thank for such a nice specimen?
