I saw several posts about GFS pups and Jay at Guitar Fetish being responsive, that I emailed him a question. He answered me within a couple of hours with a suggestion. That was impressive. I went ahead and ordered the "Vintage 59" set.
I bet if you emailed Jay for advice he would answer. I used the contact link on his ebay site. His reply had this email address:
