If the pitch of the note at the 12th fret is sharp relative to the pitch of the
harmonic, loosen string tension and lightly tap the foot of the bridge to
move it back toward the tailpiece. Retune and adjust as needed until the two
pitches agree.
If the pitch of the note at the 12th fret is fl at relative to the pitch of the
harmonic, lightly tap the foot of the bridge to move it forward toward the
neck until the two pitches agree.
When the harmonic and 12th fret pitches agree on both the E-strings of a
movable bridge, the instrument is properly intonated.
IMPORTANT NOTE: When re-stringing a guitar with a movable bridge and
ebony tailpiece, change the strings one at a time. Do not remove all of the strings
at the same time, as both the bridge and tailpiece are held into proper position
by the downward pressure and tension of the strings.

Use the handle of the TonePros

wrench (provided) sideways in the groove
of the stud tops to tighten and loosen the studs. The stud tops should be
snugly tightened so the bridge is not leaning under string tension, yet loose
enough to adjust the longitudinal set-screw. After adjusting the set screw, use
the open end of the wrench to adjust the bridge height. Now adjust each
string saddle as needed to intonate the guitar.
