I just ordered a RG8670 in transparent blue yesterday, and Koichi from Ishibashi told me that mine would be the last one in that color ordered by Ishibashi from Ibanez since that model was just discontinued. He didn't mention any other colors.
I was really torn over which color to order - the blue or the black onyx. I hope that Ibanez comes out with another model like that one (even if they don't want to bring them to the US) so that we all could have an option of ordering a J-Custom in black onyx. Any word on new J-
Custom models for 2005?
