Phew. Long delay - but I've been hard at work. I've been spending a lot of time working on the frets on this guitar, and I've fashioned 320, 500, and 1000 grit straightedges to attempt and get some backbow.
Without going into an insane amount of detail, the guitar doesn't naturally have relief in the neck. It's always straight. To make all the notes not just buzz out, I'm leveling the frets while the guitar is held in a backbow. Then, when the neck is released, the guitar go back to being straight, but with the slightest amount of upbow. It's been pretty cool to see the guitar go from not play well, to being pretty good.
I still need to work on my fret crowning, but I don't have the tool for that. I might need to fabricate something.
