Just finished basic sanding of my new bass body (will post pics soon) and I began to think. I was originally going to put LEDs as fret markers using a bolt on. However, my body is increadibly small so I figure that a set in with a neck that extends beyond the end of the fingure board will better suit me in this case. Here's my question. I have no experience with set ins. How do I do it? That is, how do they differ from bolt ons both in shape and assembly? Do I need anything other than glue to hold the neck in? And most importantly, will it last over time?
