Yes I understand WHY mods exist but having owned SR5s in the past it's never occurred to me on any them to change out the neck. I ask to understand WHAT the "improvements" if any are. Your response to @roger highlights and answers my question. Can I ask why then you still prefer wooden necks? I learn a lot from this forum being far from an expert 👍If I have any "issues" with SR5s it's the narrow (to me) string spacing,the necks always felt great.
