Yes you can do that. The EBMM EVH model that I have is notorius for the E string slipping off the fretboard and my guitar tech did the same thing (as above) and hasn't slipped off once since it's been done............rgr said:The trem looks kinda off in the pic, but it may be the angle. Yes, you can loosen the screws some, don't loosen them all the way, and shift the neck. It's a common thing to do on bolt-on guitars, an old guitar tech friend of mine showed me many moons ago.
