Question on which trem to use

[Cjpalo]

It seems I have too many projects going on. I'm in the process of restoring my Charvel 750XL but today I found a great deal I couldn't turn down. I picked up a Jackson PS-4 body for $30, it's in ok shape but im still gonna strip it and repaint it. My question is what trem did these models have and what would be a good upgrade for it that will fit in the trem routing thats already there?

It came with a JT500. A JT590 (looks like a JT500 but says "Jackson" and "made in germany" on it) or Schaller (also looks the same and says "made in germany") are direct swaps with no other mods.

^^ +1 to everything.

Swapping to an OFR or Gotoh will require modifying the rout and may knacker up the intonation (unless the bridge was misplaced, which wasn´t too uncommon on performers..)
