That would please me. When I bought the H535 with P90s that Kuz sold me, he already took care of the bridge mount with the Faber screw in ABR inserts! He and I are both so OCD, I just knew when the guitar got here, that it would set up as good as it could be, and I was right, it was I waited a long time till I got a semi-hollow Heritage, and I'm glad I did. I seriously doubt a custom core would be any better than this one...
