Old post, but I read some answers and appreciate the competence of many people.
Question: when I bought my Epiphone DR100 it was a loud strummer and no more, because the action up the 10th fret was so high you could only use chords.
I've changed 3 bridges and lowered the action, plus I ever used .010 gauge for easy bending. The guitar is fine for what is worth but buzzing begins to appear at the 12th fret, 1st string. I'm thinking to go back to 12-53 and put some strain on the neck, without tampering on the truss rod but simply wait for the strings to pull and raise the action. I always feared to touch a truss rod!
What do you think of this approach? Thanks & best regards
