Thanks for the info.A lot of different MIJ models had that bridge available and during the era that matches that serial 84-87 MIJ or 88/89 USA. The routing is kind of weird between the kahler and the bridge pickup though. The spacing of the dots at the 12th look MIJ as well as the black truss plug, but could be wrong. Better pull that guard and check the routing, maybe pull the neck too when it arrives. I hope I'm wrong and you didn't get taken.
It looks like what they call the Steeler.Isn't that the same kahler they used on the HM Strats? I've always heard those were pretty killer
