I started with the JD1 in the original crop, I was intrigued by how interesting it was, and thought it looked awesome. I sold it after a few months though, once I saw they were going for twice what I paid for it, with the intention of buying a "free" bass the next year since they had said they would do more runs.
Last year, for my free bass, I grabbed the JD2 in black. I saw a lot of JD1's with very poorly matched grain and didn't want to risk it happening to me, so I went with black. I didn't have a jazz bass and have always loved the Caprice, so it made sense to me, and I still love it. It's very well made, I have the action low with no issues, and now that I have a Fender Jazz as well, it turns out that the JD2 sounds completely different, much more P bass-ish, so it doesn't overlap much.
No regrets, I got a very unique bass that I love, and I would still be just as happy had I actually paid for it.
