Your Fly has been shipped with D'Addario .009 > .042
strings adjusted to a very low action of .070 on the bass side and .050 on
the treble side, measured at the twelfth fret.
If you lower your action even further, be aware that
some buzzing may occur.
The Fly's bridge is designed and made exclusively by
Parker. The radius of the bridge exactly matches that if the neck. Therefore,
the Fly doesn't require the individual height adjustment devices that detract
from tone and sustain.
Action is set with three screws from the back of the
guitar. Using the T-handled 3/32 Allen wrench supplied
with your guitar, turn the screws clockwise to raise the bridge and
counterclockwise to lower it. Since these screws also adjust the angle of the
bridge to the guitar, to make more than a small adjustment you must adjust all
three screws a little at a time, being careful not to tilt the bridge in its
cavity. Do not adjust more than a ¼ turn at a time.
