When did Gibson first introduce Custom Buckers? I have a 2011 Les Paul Custom 1957 reissue in White. Kind of a rare bird as I haven't seen a '57 in this color before. I removed the pickups to see what was installed and they are dated 11/21/2011 Custom Buckers in both neck and bridge. They sound great. A little hotter than the ones in my R9/R8 historics.
