What size allen wrench to adjust pickup pole pieces on EBMM John Petrucci?

[dolinja]

Hey all,

In follow up to my initial questions from a few days ago, I want to try to raise the pole pieces of the bridge pickup to get a hotter signal on my Petrucci Music Man. Unfortunately this guitar was used and didn't come with the allen wrench. Could someone advise as to what size allen wrench should be used?

Thanks!
Jason

It didn't come with an allen wrench for the pole pieces when it was new. You would be better off shimming the pickup
