Being dissatisfied with the action on my new Stagg, I gave the truss rod a good 1/4 clockwise turn, and lo and behold, I was able to lower the action lower, and lower . . . and lower . . . I finally got the E string side of the bridge to rock bottom without getting buzz. The D string mwahs all the way up and down the fingerboard, so I can't go any lower, but now the string height is just below 10 mm all the way across!! Gotta be careful about how hard I pluck now, though.
Thanks to radula for his post on how to fix that annoying endpin rattle. Stupidly easy fix.
And thanks DoubleMIDI for all of your posts regarding string recommendations. I'm thinking 4/4 Spirocore Lights?
