■ What is the FretwaveTM system?

FretwaveTM is a new remarkable intonation system that im-

proves the intonation throughout the range of the fingerboard.
This system was developed to correct the mismatch of har­monics and fret position alignment inherent on all fretted, string
instruments that utilize the standard fret position formula and
typical tuning methods. Simply put, this is what causes chords
to go out of tune as you change positions.

■ Why it works :

The Fretwave
and degree of the bend underneath the G and B strings are
designed to compensate for the differences between the har­monics and the mismatched fret positions.
These
hand fingering techniques.
The bent frets
tuning method (required for the best results) adjusts the pitch
for each string while compensating for the other fret positions
throughout the fingerboard.

■ How to tune the system :

1.) Tune your guitar using your normal tuning procedure
(scope).

2.) Tune the 5th string (A) fretted at the 5th fret compared to
the open D string (unison).

3.) Tune the 6th string (E) fretted at the 5th fret compared to
the open A string (unison).

4.) Tune the 3rd string (G) fretted at the 2nd fret compared to
the open D string (5ths).

5.) Tune the 2nd string (B) fretted at the 3rd fret compared to
the open G string (5ths).

6.) Tune the open 1st string (E) compared to the 2nd string
(B) fretted at the 5th fret (unison).

Use the open chords below to confirm the tuning between
chords. Using your ears, make fine adjustments as required.

Once you have experienced the benefits of the
you will be amazed at the tuning accuracy, especially when
you go back and play a standard guitar without the com­pensated
