For what it's worth, the tutorial here on "Fretboard Removal" has proven extremely helpful. I didn't know anything about removing and replacing fretboards 6 months ago, and since then, I've successfully removed and replaced the fretboards on two guitars. However, both were bolt-on necks.
My question for those more seasoned here - wouldn't many of the same steps in that tutorial apply for removing the fretboard on a set neck?
I'm guessing, if lacking the space to insert a razor and knife beneath the fretboard at the body end, might one might start at the nut?
In any event, much gratitude to Kevan for writing that tutorial.
