Graph Tech ResoMax Wraparound Bridge - Manual

Determine correct string height by measuring the gap
between the top of the 12th fret and the bottom of the low E
string. It should be around 0.125” (3mm), or about a stack of
a 12 cards if you don’t have a ruler. For the high E string, the
gap should be around 0.080” (2mm) or about a stack of 8
business cards.
Remove the strings and remove the old bridge by sliding it off
the posts. The ResoMax bridge comes with steel posts that
enable the magnetic AutoLock feature. You may keep using
your old posts if they are also steel.
Adjust the two set screws at the back of the bridge so that
the range of travel of the saddles is beyond the scale length
measured from the nut (scale length is 2x the distance from
the nut to the 12th fret).
Install strings and tune your guitar to concert pitch. Adjust
the string height by turning the bridge posts with a coin.
Raise or lower the treble and bass sides of the bridge until
correct string height (measured in Step 1) is achieved. Tune
the guitar to concert pitch after the adjustment and check
the string height at the 12th fret.
Set the intonation. In order for the chords to play in tune all
over the fretboard, each string must be correctly intonated.
The note fretted at the 12th fret should match the 12th fret
harmonic. Compare the pitch of the fretted note and the
harmonic (lightly touch the string right above the 12th fret
and pluck). Adjust each saddle by tuning its intonation screw
with a screwdriver. Shortening the string will increase the
pitch of the fretted note relative to the harmonic; making the
string longer will decrease the pitch. Each time you make a
saddle adjustment, retune the string before comparing
pitches again.
