Enhances volume Flattens 'bellied' soundboards A unique solution to a common bridge problem, this spruce device attaches beneath a guitar bridge. An adjustable spruce "pressure post" rests against the tailblock, providing leverage to flatten the soundboard.
See details below
The spruce block is 3/4" x 1-5/8" x 3-3/8" tall. The 1/4"-diameter tension rod is 9" long. The mounting post has three different positions to accomodate a variety of bridge styles. #3694 includes a white pearl dot to hide the bridge screw.
Screw mount: This spruce device attaches beneath the bridge via an inlaid screw. An adjustable spruce pressure post rests against the tailblock, providing leverage to flatten the soundboard. Better bridge contact and alignment can also enhance sound projection.
Brass pin mount: The pin-mounted version of the JLD Bridge Doctor attaches beneath the bridge using a threaded brass bridge pin. The strings mount horizontally through the tops of the matching brass bridge pins (included).
February 2, 2009 The Bridge Doctor device is amazing. I own a 17 year old Alvarez Yiari (which now sounds awesome) and a 1981 Guild D45 for which I am ordering my second Bridge Doctor.
