How to Adjust the Intonation on the Jamstik Classic, Standard and Deluxe

If you notice that notes higher up on the neck sound out of tune (typically above the 12th fret) while the guitar is in tune when playing open notes, then you will need to make an adjustment of the saddle holding the string at the bridge of the guitar to correct the intonation and increase the accuracy of pitch across the fretboard.

Also, note that if you change the gauge of strings it may be required to adjust the intonation to ensure accurate pitch across the fretboard.

Tools needed: 

- Philips Screwdriver 
- Tuner

1. Check pitch of open note & at 12th fret

First, using a tuner check to make sure that the guitar is in tune.

Then using a soft to medium pick attack play the lowest open note (or harmonic note at the 12th fret) then compare the pitch to the pitch fretted at the 12th fret; If it is more than a few cents off then an adjustment is warranted.

2. Detune and adjust the string saddle accordingly

To adjust the string, you will need to loosen the string slightly to remove some of the tension on the saddle to allow it to move more easily. Now time to make an adjustment!

If the fretted note is sharp: Adjust the saddle towards the bridge by tightening the screw that holds the saddle on the bridge. (Turn clockwise)



If the fretted note is flat: Adjust the saddle towards the headstock of the guitar. (Turn counter clockwise)



Once the saddle has been adjusted, re-tune the string & check the pitch of the open note against the 12th fret pitch, and repeat this process as needed until you are within a few cents.

3. Repeat for each string 

Repeat this process for each string as needed.
