As the Forum-proclaimed expert, I'll handle this one...heh heh....
Production totals on the J-Customs are tight. *My best guess- 12 or less per model.
Materials used: top of the line. *Even the guys over at Vigier go, "Damn, nice work!". *
The J-Customs are hand-assembeled, hand-finished, hand-wired, hand-everything in Ibanez's J-
Custom shop (where the JEM's, UV's, JS's, etc. are done as well). *Only the best luthiers Hoshino has touch these things. * It can't get much better.
For more info (and pics), check out the quick page I put up last year:

I bought "www.j-custom.com", but the site's not up yet. *Soon, I promise. *:-)
