Filling An Acoustic Guitar Saddle Slot to Correct Intonation
The
most common reason for recutting the bridge saddle slot is
to change it's position and correct intonation (mathematical
layout). We also find it necessary when using pickups that
require a wider slot or even to repair damage done by someone
with a bad idea.
A "fill" is made which matches the bridges
material (ebony in this instance) and grain line.
The fill is epoxied into the slot.
The excess fill material is planed level with
the bridge and it is sanded and prepared for slotting.
This slot was angled for proper compensation
and intonation
as well as widened to accept an L.R. Baggs LB6 saddle pickup.
In order to slot a bridge I use a jig which clamps to the top of
the instrument and serves as a guide for my laminate trimmer. It is fitted
with a carbide, downcut bit and is lowered into the wood slowly.
The plexi-glass base mounted to the base of the laminate trimmer
slides along the route in the jig which insures a straight line
and level bottom for our new saddle.
