Ok, then I just have a somewhat unrepresentative collection of modern day post-1986 Birds as my 1997 sunburst TBird, my 2000 Blackbird and my 2006 Gothbird all have ebony boards, with only the 2007 Zebrabird being the exception from the rule. And now the Nikki Sixx Sig is another ebony one (probably, I'll check tonight). You live and learn!
My sixties Birds, the Bicentennial and the 1986 one pup TB II (former) "Georgebird" have all rosewood boards though.
