With a little guidance and a lot of patience I figured out how to adjust the intonation and truss rod on my Sheraton ll. With a lite luck I may try cutti g and shaping a new nut for a Gibson.
It's actually not too bad once you figure it out. Truss rods were a bit more intimidating at first, with the chance of going too far, but easy does it. I haven't tried shaping a nut.
