Hi, I recently acquired a JPX and love it, but I'm more of a Duncan guy, so I wanted to swap the Di Marzios. The construction is mahogany center block with chambered alder wings, maple top( ???), and the neck is mahogany with ebony fretboard. I think it has stainless steel frets. I have a 59/custom hybrid that I recently bought, and a Pearly Gates set, along with 59's. I also have a '78 zebra, but I was thinking of putting it in a '84 Kramer Baretta. What do you guys think?
