Mentioned this kit a bit in my GS-2Q build diary, starting one for it now. It's definitely going to be a project.
At a quick glance it almost seems innocent enough.
Broken corner on the neck pocket. Humbucker route also needs to be finished.
Corner of the fretboard is in bad shape, and the neck angle is wrong for a hardtail.
Upper fret access is non-existent. This is one of those oversights that can pop up with a custom.
Step 1, gluing that corner back on. The corner piece itself is rough looking, so once it's dry I'll probably have to do some shaping to make it look decent. Probably round it off.
Once that's done I will probably do something about that nasty fretboard corner. Maybe I can use some ebony wood filler on the side. And caaaarefully try to get some glue in the split part and clamp it so it's flat.
Thinking about cutting off a section of that upper horn to fix the fret access. Right now the angle of horn goes down to the 22nd fret and curves back up at about the 19th fret. After the 18th fret you have to start reaching up.
Right now I'm thinking adjust that angle so it goes approximately to the end of the fretboard, and curves back up to around the 23rd fret, close to the neck pocket and just enough to avoid a hard angle that wouldn't fit with the curved angles elsewhere on the body. Would get rid of most of that side of the neck pocket, but it's bolt on so I don't think that would be a problem.
