Instruction 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.
