2. Adjusting The Intonation*
Intonation adjustment is usually only necessary
when different gauge strings are used (it can also be affected by the angle
of a tremolo unit). The saddle positions are adjusted by the individual slot-head
screws located on the front of the bridge, sliding the saddles forward or back-
ward. To check the intonation: Use an electronic tuner and tune the guitar to
a standard pitch. Play the harmonic at the 12th fret, and compare it to the fretted
note at the 12th fret. These notes should read the same on the tuner.
If the 12th fret harmonic pitch is lower than the fretted note, slide the saddle
back (toward the tailpiece). If the 12th fret harmonic pitch is higher than the fret-
ted note slide the saddle forward (toward the neck).
* Adjusting the intonation and string height will affect the playability of your
guitar. If you are unsure of any of the above operations please take your guitar
to an experienced guitar technician or contact GBME.
