Hi,
What kind of string do you use on your EBMM Petrucci guitar ?
Did you have any issue with string gauge ?
For which gauge the guitar is originally set up ?
What kind of string does John Petrucci use ?
Thanks
If you change to a lighter gauge, I would have to say yep....I went from 10's to 11's on one of my other ones and had to have it set up....I believe the same would apply.
