CHANGING STRING GAUGE
When changing to heavier gauge strings, the following adjustments will be
required. If you are unfamiliar with replacing the tremolo spring to match
string gauge, filing the nut slots wider, adjusting the truss rod, and resetting
the action, we
strongly
suggest that you take your instrument to your
favorite guitar technician.
CHANGING SPRINGS
STEP 1
Remove the back plate.
Exercise caution when removing the back
plate, as the l e a d w i r e s f r o m t h e b a t t e r y t o t h e c i r c u i t
board can become disconnected.
Confirm that the spring number and the string
gauge match.
For example:
Spring number 9 for .009 – .042 strings
Spring number 10 for .010 – .046 strings
STEP 2
Move the step-stop down into the H O M E position.
STEP 3
Tighten the spring against the step-stop with the
balance wheel until about ten threads are showing
(approximately 1/2” or 13mm).
STEP 4
Tune your Parker guitar to pitch.
