I had one a little over a year ago. Absolutely loved it. One of the best sounding basses I've ever owned. To me, it doesn't sound like a traditional thumb much at all. I think the pickup placement is the main reason. To me, it sounded (unsurprisingly) very similar to a streamer or fna Jazzman. Of course, the woods change it a little bit, but I'm speaking more in terms of a general tone. It is, however, the best looking thumb they've produced I think.
