The Saddle is a rather simple part, yet it is critical to the tone, playability and even the tuning of your guitar.
A saddle may need to be lowered if your action is too high. If it is too low, it can be shined, but we really prefer to make a new saddle in this case. You may also need material removed from your saddle if an under saddle pickup is installed. On the subject of pickups, under saddle pickups work best with the full downward force of the string tension. To achieve this, the saddle should have a loose fit in the bridge slot. If no pickup is installed, it is preferable to have a snug fit to improve the acoustic guitar’s tone as well to avoid putting unnecessary tension on the bridge which may cause a crack to form.
Aside from adjusting the action, many players prefer the tone of Bone over plastic. In this case a custom bone saddle can be made. Another popular option is to add a compensated saddle, or compensate your existing saddle, The “B” string benefits most from compensation, though all strings can be compensated to some degree for improved intonation up and down the neck.
