Thanks guys, I'm pretty happy with it.
Just spent all night setting it up, and I got it as close to done as I can. There are a few frets that need to be crowned better at some point, and my nut files don't go as wide as the low C string (0.056") so I dodgied up my own which did an ok job, but not perfect. I was going to cut a new nut anyway, so might try to find a file of the right width online.
It feels pretty good to play, and is a much nicer guitar to have in a drop tuning than the cheap strat copy I rescued from the tip (like, can it even stay in tune?)
