I held the white up against it, didn't look too bad. Decided to stick with that for now and change or stain it later on if I didn't like it.
So anyway, the finish ended up being a fairly smooth semi-gloss, felt OK today, so I assembled everything.
Looks OK. Plays very nicely. Action's a tad high but I'm sure I can correct it after everything settles. Not as pleased overall with this as I was with the fretless bass, but as I keep reminding myself, this was the first try even though it's taken a lot longer (4 months, wow) so the initial work I did wasn't as good and I don't think there's a way past that without sanding it all the way back to nothing and starting again. Which isn't happening.
That said, the bits I would do differently are all in the finish. It plays fine. I'm a big fan of the sound from the neck pickup. The bridge is OK I guess and both together are fine but nothing special. Overall, I'd be perfectly happy if I'd bought this guitar completed for the price I paid for the kit and materials.
And here's a demo. Drums are one of the demo tracks from Addictive Drums 2 (I'm no good at programming drums, but I've had a go altering stuff so it's not totally generic), bass is the fretless kit, and the guitar is this one. Neck pickup only, run into a Komplete 6 interface and Guitar Rig because I don't own a guitar amp that's worth recording. Playing's just some somewhat uninspired messing around over a simple blues bassline. I'm sure it'll be obvious that I'm not primarily a guitar player.
