RESOMAX™ BRIDGE INSTALLATION INSTRUCTIONS
1
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 12 business
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.
3
Install strings and tune your guitar to
concert pitch. Adjust the string height
by turning the the thumb wheels on the
bridge posts. Raise or lower the treble
and bass sides of the bridge until correct
string height (measured in Step 1) is
acheived. Tune the guitar to concert
pitch after the adjustment and check the
string height at the 12th fret. If the
strings touch the bridge body behind
the saddles, raise the tail piece until the
strings have clearance, by turning the
screws on the tail piece mounting posts.
The ResoMax bridge has a one year warranty against manufacturing defects

Remove the strings and remove the
old bridge by lifting it off the posts. The
ResoMax™ comes with posts, but in
most instances you can keep using your
old posts. Lower your new ResoMax™
bridge onto the posts. Set the intonation
“starting point” by adjusting the
intonation screws so that the saddles are
close to the center of the bridge.
4
Set the intonation. In order for 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 turning its intonation
screw with a screwdriver. Shortening the
string will increase the pitch of the
harmonic relative to the fretted note;
making the string longer will decrease
the pitch. Each time you make a saddle
adjustment, retune the string before
comparing pitches again.
