Hey guys, my acoustic is having a problem where the 10th fret on the high E string produces the same sound as the 11th. I have to press the fret down harder than normal for it to produce its correct sound. What kind of adjustment should I make in order to fix this issue?
Try adjusting the truss rod or lowering the frets somehow. Chances are, it is because of the action being too low. My guitars did that a while back, but over time, they stopped for some reason.
