*NOTE: This product is the "JLD Bridge System" which requires one small 9/64 hole to be drilled through the bridge. Complete instructions come with the install kit, which also include diagrams. Below shows the "JLD Bridge Doctor" which does NOT require any modification to the guitar. Message me if you have any questions.BEST PRICE on ebay!!! Don't be fooled by a LOW price for the item, then a HIGH shipping price by other sellers!!! BEST PRICE on ebay!!!Guitar strings constantly pull up and forward with a force of
approximately 250 lbs., ultimately causing the top on your guitar
to warp. JLD Guitar Research and Development, Inc. has patented
a simple way to remedy bowed tops. The JLD Bridge Doctor installs
easily through the sound hole in minutes and requires no modification
to the instrument.
The above shows the effects of string tension on a typical guitar.
There is a pronounced bow behind the bridge and a dip in front
of it. The saddle has been filed down to keep the action playable
as the top has come up. Because the bridge pin holes are almost
even with the top of the saddle, the strings don't exert much
downward force on the top.
This guitar is hard to play and has a weak, thin tone.
Above is the same guitar with a JLD Bridge Doctor being installed.
The bridge pins have been replaced with a set of pins similar
to the one shown at left. The JLD Bridge Doctor has been inserted
through the soundhole and is held in place by one of the new bridge
pins which has been threaded into the top of the Bridge Doctor.
A small locknut keeps the additional pins in place. Strings now
pass through holes in the sides of the pins instead of being inserted
into the bridge pin holes.
Here, the JLD Bridge Doctor has been adjusted to counteract the
pull of the strings and the warpage of the top. The top is permanently
flat and a playable action has been restored. The strings exert
proper downward pressure on the saddle - enabling them to transmit
more vibration to the instrument. The Bridge Doctor is also acting
as a soundpost - transferring string vibration to the body woods
directly from the bridge.
The guitar is completely unmodified and is not only easy to play,
it will now have more volume and sustain and a richer tone than
it ever has before.Look inside any Breedlove Guitar
and you'll see a JLD Bridge System.
