After finally getting to the stage where I could put on the strings and tune up for the first time, I've had about a good week to really enjoy playing my first build. I connect the pickups with alligator clips, and it sounds and feels great! However, the action is fairly high - didn't get exact measurements, maybe 5/64 at 12 fret (e.g. top of fret to bottom of string) - and while I always thought that action should be as low as possible without fret buzz, it turns out that I really enjoy the feel of it. While it's totally different from my other electric (a Les Paul copy) which has the action set as low as possibly, it's somehow very playable, has great tone and feel, and I'm not sure I want to mess with it for now! (This is all with a set of 9-42 strings so far, if I go to a higher gauge maybe I'll feel differently.) But, even if I wanted to leave the action that high, the nut is going to need some adjusting no matter what: It's SO high at the first fret that just on the first couple of frets it's not very playable and the intonation is way off. What is the better approach in this case (pics below)? File the slots? I don't have proper files, but from reading around I could use a combination the wound strings for those slots, various sandpaper/feeler gauge methods. Also, I could order some files, they will take a few weeks to arrive... Take it off and sand down the bottom? Assuming that I can get it out somehow without breaking it, and assuming that it is flat-bottomed, which I don't know yet.
