1 Checking the nut action

This is a nice Telecaster copy, but some of the nut slots have been cut too low, and open strings are giving that sitar-type sound. I check the nut slot height by fretting between the second and third fret, then seeing how close the string is to the first fret. If it is touching it, the slot is too low, and if there is a big gap it makes it difficult to play, especially with open chords and barres up to about the third fret.
