I could be finishing my first full build, or even working on my RG350 mod, but fuck it, why not start taking apart one of my other guitars and not finishing it. So this was my very first guitar that I got almost ten years ago, it's an Eterna ES-31 made by Yamaha. Pretty cheap acoustic but it sounds quite decent, I was just not a fan of how it played so I haven't played it much at all these last few years. So I decided to buy some new tuners (Gotoh Vintage ones), a graphtech Tusq nut, ebony bridge pins as well as an ebony endpin just for kicks. Also got some fret files and such so that I can learn how to crown and level frets and hopefully make this guitar play more smoothly. So this is what it looked like before: So the fretboard has never been cleaned on this guitar and was pretty goddamn disgusting. So that was the first thing I did when I took the strings off: broke out the lemon oil and let the fretboard soak in as much as it could over the course of a few days, I think it's a lot better now. Did the same to the bridge but it wasn't nearly as dry. Took out the old tuners and knocked out the bushings, unfortunately this resulted in some chipping on the top surface so now I need to put some kind of veneer or top plate on it, luckily I have a piece of figured mahogany which should do. The new tuners are too small to fit in the holes so I filled them in and will be redrilling them. Also knocked out the old nut, didn't come out as easily as I thought it would but then again I was holding the guitar with my knees and trying to use a hammer and punch with my hands. So here's where I am at today: Hmmmmmm wonder what kind of wood is under that finish. The good news is that the sealer and clear coat aren't very thick at all. I'm pretty sure I got to the bare wood in less than 5 minutes of hand sanding with 60 grit, so a power sander should make short work of that finish on the back of the neck and then I will oil it up later. I'm kind of considering sanding the back and sides of the body and oiling those too only because the finish is chipping around the edges but I don't think I will. I wanted to do a reasonably quick and easy mod for this and ran into more trouble than I wanted when the new tuners were too small, plus I don't want to go through the headache of sanding the finish between the neck and body joint. SO, here's a list of what's happening with this mod: New 15:1 Gotoh Vintage Oval Knob tuners. Replacing old plastic nut with Graphtech Tusq. Replacing old plastic bridge and end pins with ebony ones. Sanding gloss finish off back of neck and oiling it (probably tung oil). Putting figured mahogany cap on headstock. Cutting the top of the headstock in some way so that it isn't just a goofy looking square.
