Re: Old Ibanez RG550-570 necks
Had a little time on my hands, so I did some research on head stock colors.
Mostly I looked at all of Rich's catalog scans.
Below is what I came up with and by no means the end-all beat-all answer.
Ibanez has been known to throw out some weird stuff depending on what country it is.
1988 - Known as the Roadstar the maple boards were color match. All else were black.
1989 - All black
1990 - All color matched
1991 - Except for the 550FM, all color matched
1992 - Except for the 550FM, all color matched
1993 - Maple boards were color match. All else were black.
1994 - All color matched
1995 - All black (catalog was light in pictures)
1996 - Assume black (only had 1 pic of a 550)
1997-present - Black.
I know someone will chime in that "...my '99 has a color matched headstock, dumbash!".
I only looked at the 5xx series, but did see that the 4xx & 3xx series had color matched headstocks where the 5xx's did not....meah...flame on.
