Just picked up my new Martin acoustic. Plays nice but the action up around the 12th fret seems high? (Maybe just me?)
Just under 4mm at the 12th fret?
Relief is fine...tiny bit of play. Is 3mm normal at the 12th on an acoustic?.
hey now.....we dont adjust action with the truss rod.I'd say slightly high normal range....2 to 2.5 might be better...the saddle might need sanding / shaving......or you can tighten the rod a little bit to get no play...just before you get to backbow country.....and see where you end up and see how the notes in the middle of the fretboard ring out....before doing something irreversible or paying someone else to do it....
Looks high to me, but from what I understand, most Martins are set pretty high from factory.
When I got my brand new 000-17, I immediately brought it to my guy and he adjusted truss rod, and a slight saddle trim and it was perfect.
