relocating a saddle
Many guitars lack the proper compensation needed to provide accurate compensation. If ramping the saddle fails to adequately extend the string length the only remaining remedy is to relocate the bridge or the saddle slot.
The saddle slot is first plugged with matching wood. In this case Brazilian rosewood.
The plug is carefully shaped to fit precisely.
The plug is epoxied into the slot.
The location of the new slot is drafted on white tape.
A routing jig is constructed. A plastic jig is available for purchase at Stew Mac.
Great care and focus must be applied to the operation.
The slot is created with several passes until the depth of 3/16".
When all is done the repair is practically invisible.
Locating the saddle closer to the bridge pin holes affects the break angle of the strings. This must be considered. If the break angle is too steep the procedure should not be prescribed. The break angle in this case is ideal.
Aside from playing "in tune", accurate intonation increases sustain. Increasing the break angle of the strings has the additional benefit of increasing volume and clarity.
