| Setting the Intonation (Guitar w/adjustable bridge) |

|
Setting the Intonation is the process of changing the measured (fixed) scale of a guitar by adjusting the string length. This is most commonly done at the bridge of the guitar. In adjusting the string length, we're trying to get the 12th fret note (the half way point of the string) to sound the same as the open string (the 12th fret note is 8 notes away, but the same note).
You should intonate the guitar after the nut, bridge, and neck adjustments are done!
You will need an electronic guitar tuner and a screwdriver which fits well into the bridge saddle screw. The bridge saddle is the part of the bridge on which the string rests.
1. Plug into the tuner.
2. Play the open 1st string and look at where the reading is on the tuner. Do the same thing for the 12th fret note. If the 12th fret note reads below (a lower pitch, or flat) the open string, you need to move the saddle forward (toward the pickups), shortening the string.
3. If the 12th fret note reads above (a higher pitch, or sharp) the open string, you need to move the saddle back, lengthening the string.
4. Repeat steps 2 and 3 until the open string and 12th fret read the same on the tuner.
Once in a while you might get a "bad" string. This is a defective string which will not intonate properly. If this happens, throw the string out and get a fresh one. |
