JLD Bridge Doctor

About This Item

• 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.

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.

Screw mount: This spruce device attaches beneath the bridge via an inlaid screw (a white pearloid dot is included to hide the bridge 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).

StewMac Tech Tip: We recommend the brass pin mount version for 12-string guitars.

Great gadget.

(Customer's Reviews)

I had a 1/4 bulge in my yairi top .it definitely helped to stabilise the top but did not take all of the bulge away. It does change the sound . More low end comes through.if that's what u want then I guess that's a good thing... simple to install.however drill the countersink hole first it prevents the bit from tearing through your bridge and top especially if you are using a elec drill.. hope this helps someone. Peace.


Worked perfectly

I purchased a vintage Yamaha 12 string. I knew it had a serious "belly bulge" when I got it. After seeing several reviews and a couple of YTube videos on the JLD Bridge Doctor, I decided to take a chance and ordered one from StewMac. It arrived as promised. The guitar was very dry (which probably caused the bulge), so after about a week of damp sponge in sound hole, I installed the Bridge Doctor. It took a little longer than 30 minutes because I was very cautious. In the end and top was FLAT. I am very pleased with the results.
Anyone considering this should be VERY CAUTIOUS when you drill the holes in the bridge. DO NOT drill all the way through the bridge with the larger drill bit. Just deep enough for the screw head and the inlay.
CONS: The instructions that came with it could be a little better explained. I read them multiple times and watched more installation videos on YTube before I started.

I own a Breedlove Solo Concert and it has a very similar unit in it as the JLD Bridge System. I used the pin mount version #3695. I spent two weeks slowly humidifying the guitar in a hardshell case without strings on it before installing the bridge system. Once installed I spent two days making small adjustments before restringing. It's not a "fix all" as my action now has to be readjusted but my 34 year old guitar is once again playable and well within the realm of fixable with minor adjustments to the bridge and nut.
