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.

Exceptional results!

I received a Washburn Cumberland in for setup and repairs, but the pot-belly was huge, and the saddle had already been filed down wafer-thin. The action was too high to even think of correcting it. I discovered the JLD system online, ordered 3 (!) and installed it. It brought down the back of the bridge only, and I figured it was not going to work properly. I restrung and set up as best I could, but was not happy with the result !! I left it overnight, and when I checked it the next day, the string tension had positively affected the cantilever design of the JLD! The front of the bridge had pulled down overnight, resulting a really slick action that I NEVER imagined I would get on this guitar! Great innovation for a big problem!

This is the second JLD I've installed; good instructions and it completely removed the belly the guitar had. Now if only it'd work on mine.... It also sounds much better. More projection, and fuller sound.

I repair guitars as a hobby. I have installed the JLD Bridge Doctor in three guitars to correct minor belly bulge, and two were factory installed in my Breedloves. Each time there has been a noted improvement in sustain, volume, and clarity, as well as taking care of the bulge. As effective as it is easy to install, I don't use them just for repair anymore.

Nice device for the small-handed

Installed the screw mount version in a Harmony Sovereign H1203 with one of the worst belly bulges I've seen. As others have noted, it did bring the bridge down, but did not completely flatten the top - but I didn't expect it would. Nice improvement in playability and tone. BUT, I have large hands and doing the install was much more difficult for me than for others who have rated this device. As for so many through-the-soundhole techniques, think twice if you have very large hands.

I have installed a Bridge Doctor on two guitars: a late 70Æs Ibanez Concordùwhich is a copy of a Gibson Doveùand a 2010 Gibson SJ200 Studio. The Ibanez got the screw mount model of the Bridge Doctor while the Gibson got the brass pins. The Ibanez was bellying a bit and the Bridge Doctor corrected that quite easily. The Gibson got the device primarily as a preventative measureùI saw a vintage Gibson Jumbo that was bellied quite badly so after the positive results with the Ibanez, I figured the Bridge Dr. would be a good way to protect my more expensive guitar. I didnÆt want to drill a hole in the Gibson, though, so thatÆs why I went with the brass pin version.

On neither guitar did I notice an astonishing improvement in tone as some people have reported, including the manufacturer; to be fair, itÆs hard to imagine anything astonishingly improving the tone of a Gibson Jumbo. I had read some discussions of this device in which people were wondering whether the lessening of the string break angle over the saddle when using the brass pins instead of the regular bridge pins might adversely affect tone, so I did a little experiment: I initially installed it using three brass pins (6th, 4th, 2nd strings) and three (5th, 3rd, 1st) regular pins. This did not result in any kind of unevenness in volume or tone quality or response from string to string. I see that one reviewer did have problems with the change in break angle in the case of a low saddle, but on a standard saddle there shouldnÆt be a problem.

I recommend the Bridge Doctor if your guitar has a belly problem or if you'd like to keep it from developing one.

The bridge on my '88 Yamaha FG335 was starting to lean towards the soundhole and the body was bulging pretty bad. Installation took around 1/2 hour and was pretty easy. It only took a few turns of the allen adjusting screw and the body was flat and the bridge was back in place. I noticed a more balanced sound and the action was improved. I would recommend this product if you don't mind drilling through your bridge.

The right fix for my Kiso Suzuki guitar with lifted bridge. Piece of cake, I was back in the saddle, pardon the pun, in no time ;)

Instructions were easy to understand, the item was fairly easy to install and it performed as advertised. It was great to play that old 12-string again.

I've used the JLD Bridge System, the one that requires on to drill a hole in the bridge, three times in the past with great results--great tone and restored low action. This time I tried the Bridge Doctor with the brass pins, despite the cost. In this case, it was a mistake.

With a bellied top, often the saddle has already been lowered in an attempt to make the guitar playable. This was the case here. The string holes through the bridge pins result in a string height that is somewhat higher than when the string goes through the top. The result was that none of the strings have enough string break for the best tone, and two of them are barely touching the saddle, resulting in buzzing.

I'm probably going to have to remove the Bridge Doctor and put on the other system after drilling a hole in the bridge. I'm sure this works fine with higher saddles, but you need a saddle that is at least an eighth of an inch above the bridge for this to work. Higher yet is better.
