Dear Catters,

I am considering taking my Fender DG-16 12-string guitar to a luthier to be set up. The action has become quite high due to downward bowing of the neck that was not remedied at all by tuning the strings to a lower pitch.

Should I request anything more than an adjustment of the truss rod? (Not really accessible on my guitar and I don't want to fool with it myself.) What other adjustments are made in setting up a guitar for maximum playability? Also, are there any differences between 12-string and 6-string setup procedures?
