| How exactly will it fit? Will the last frets hang over the body, or end with the neck and fit into the pocket?
If the former, then everything should be fine, provided you don't bump into a neck pickup.
If the latter, then you're effectively changing the scale length and throwing EVERYTHING off.
If you have no idea what I'm saying, then just post a picture of the neck. Preferrably from the side. |
