: : What is the correct setting for the action on the d-15? Can adjustments be made for a low setup easily? : Dear Kevin; : Action adjustments for your guitar can be made easily, if you do the work patiently with great care. Before action adjustment, make the neck absolutely straight. Straightening the neck will lower the strings over the neck. Next, I recomend that you make more than one bridge so you can try different string heights at the bride. I found that the Martin tone was lost if the bridge was too low. After finding the bridge that works for you, lower the strings at the nut until they are about .oo4 thousands of an inch above the crown of the first fret. : Actual height of action is dependent on the construction of the guitar and the touch of the player. Heavy hands need higher action. : Finally add releif, or bow, to the neck to give the string some clearance to move. : I hope this helps. : : If you can’t do the work your-self be prepared to spend up to $100.00 for an experienced craftsman to do this work. I hope you already know someone in your area with a good reputation. How do you straighten the neck? With the rod? How do you adjust the action? Altering the saddle and nut, or the truss rod? When I bought a Martin D-15 the salesman noticed that the neck was lightly bowed, the fretboard was slightly further away from the center of the fret board. He adjusted the truss rod and it was perfect, as in strings even and very close, with easy fingering and no buzzing on any string and fret combination. He never touched the saddle/bridge or the nut…just the truss rod and he said not too much either. What do you think?
