It must be a Darwin thing. I purchased an IB-5 about 6 months or more ago, with every intention of having it done by Christmas. It's still sitting under my bed, and like you I have spent this time gathering the bits and pieces to build it to my specifications. I'm nearly have all my required parts now, other than a few parts I have on order, and maybe 1 or 2 more changes. Then the build can begin, so by this time next year I too might have a finished Bass guitar.
Nice job on yours though, it came up really well. I'll keep an eye / ear out for it.
