No, I never worked on a Bean like that, the ones that I worked on (as I recall, this was 28 years ago) were all 1000 series, koa body. Lots of folks complained about cold necks, to the point that Bean began coating them with what was (I think) a thick enamel of some sort. I don't remember if any of Bill K's had that coating. I agree about the Kramer wood inlays feeling weird...but to be fair they were rather slovenly epoxied in place, plenty of glue filled gaps and that would swell too. I bet that a super-ace job would feel fine! Just think how accurate your friend could make the fit via CNC. Then, if the inlays were around .090 thick, it would be easy to make them completely sealed for good. If he used something like Sundari it would make them even more stable!
