HARDTAIL BRIDGE
To change strings, thread the new strings through the string grommets
located on the back of the guitar and bring them up and over the saddle.
The intonation can be adjusted by adjusting the saddle forward or
backward using a Phillips (+) head screwdriver on the intonation
adjustment screw at the rear of the bridge. String height is controlled by
raising or lowering the small Allen screws using a wrench on either side
of the saddle.
ADJUSTABLE ARCH-TOP
The string height of an arch top bridge can be adjusted by turning the
thumb wheel screws located on either side of the bridge. Clockwise
lowers the string action; counter clockwise raises the string action.
As the bridge is not fixed to the body, intonation can be adjusted by
loosening the strings and moving the location of the bridge forward or
backward.
Vintage Vibrato
For best results we recommend replacing one string at a time. This will
help to avoid removing the string tension from the neck and keep the
vibrato spring under tension.
To replace the strings on the VBS80, thread the new string under the front
tailpiece retainer bar (A). On VBF70 there is no front retainer bar.
The ball end of the string should be threaded over and around the rear
tailpiece retainer bar (B).
The ball end of the string's hole is inserted into the rear tailpiece retainer
bar pin and the string should be pulled tight towards the headstock.
Releasing the string tension from the tailpiece may cause the ball end to
slip off the pin. Keeping string tension on the string by pulling it towards
the headstock will alleviate this problem.
Thread the string through the machine head and while keeping tension
on the string, wind the string around the post. Make sure that the string
lands on the proper string saddle on the bridge. Once tight, tune the
string to pitch. Repeat this process for the other strings.
