It ain't hard once you've done it several times. It just takes patients and experience.
I lowered the top E to 5/64ths and the bottom E to 3/64ths and re-intonated. Life with my Turner is now good.
Normally on most mass produced guitars the strings rise from the nut to the bridge. Not on the Turner. The nut is cut tall and the strings are almost parallel to the bridge height as it was adjusted from the shop.
Now, the strings are actually going 'downhill' (ever so slightly) to the bridge. It's a wonder that a first fret barre chord isn't sharp with a nut this high, but it's really fine. No sharpness at all. And no buzzes or fretting out while bending on the upper frets. This guitar is really a work of Lutherie art.
It plays much nicer now, and I didn't think it could get any better!
chiliD, you don't need a guitar tech, even an outstanding one. You want to find a
Luthier that will cut and seat the new nut correctly. Some of the best Luthiers are acoustic guitar builders who make nearly everything on the guitar that isn't made of metal. They could cut a nut for a Turner with no problem.
I consider myself a fair to midland guitar tech, but I would never attempt to cut a nut for any guitar. One, I don't have the neccesary skills, and two, I don't have the proper tools for the job.
