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.

I installed the Bridge Doctor to rescue a 34 year old Klira. Intonation was suffering due to bridge lift.
The tail block was rounded on this guitar and prompted the tension rod to pop off after tightening. The rod would bow under tension allowing side stress to pop it loose. A small poke with a punch would provide the necessary mark to retain the rod was the solution and perhaps could be included in next instruction revision.
I had to cut the system block to clear the guitar's back body brace. Hence had to cut the mounting post and the screw ( the screw at standard length would now interfere with the tension rod if tightened. All in all it was not a textbook install, but achieved textbook results. The bridge was showing signs of improvements as early as a few days with strings off ( while off, I leveled and polished frets.)
Its been in for 4 months and I left the guitar tuned low for that period and had already heard some nicer tone. Bringing back to standard tuning really shows the tone improvement, better highs, mid and low. This is a 24.75 scale instrument and after owning it for 34 years, had restored sound to better than new, with some nice short scale bends that unexpectedly growl a little like my LP. I'm a believer.
I expect the reduced mechanical advantage resulting from the cut (shortened height) system block, will require a lot more tension to achieve the same result, so I plan to be careful and incrementally tweak it at future string changes. I wonder at what point the rod will yield though.

Intonation is improved and I'm just stoked that I was able to breathe some new life into my old baby.

I've used the screw mount bridge doctor over the years on several guitars. It is effective and simple to install.

My 35 year old Guild D-25 was about to die from a lifting bridge. While doing homework on the fix I found the JLD system on this site. The job was done in 20 minutes. I was stunned, this gizmo flatten the top, fixed the lifting bridge, corrected the action and added violin like sustain. I could not be happier. I'm ordering two more soon.

the folks at JLD were very helpful. My cat lost the special screw, they sent one out fast. Every guitar player should know about this thing

My buddies Alvarez Yarieri's top was cracked behind the bridge. He didn't want to alter or replace the top because the guitar sounds awesome. The action was also pretty high so I suggested the JLD bridge doctor. After installing and adjusting the unit the action is much lower, the tone is as sweet as ever, and it is much louder. My buddy couldn't be happier. Thanks again Stew Mac.

I installed this on a 70s Yamaha with a laminated top that was pulled up. The JLD worked as advertised and pulled the top right down. I think the guitar has less bottom end now, however its only been a couple of weeks. I doubt if the guitar will ever sound the same, but at least it's much easier to play with the lower action.

I have a Yamaha FG260 12 string. The belly bulge was so bad I couldn't begin to get the strings low enough to enjoy playing. I shortened the bridge and the belly bulge was so high that some of the strings went right over the bridge. The Bridge doctor pulled the belly flat and also improved the sound of the 12 string. It used to be so brassy that it was not enjoyable.


Now it is more balanced and sweeter, a bit lighter and far more usable. I thought the guitar was bulging beyond reasonable costs to repair. The Bridge Dr was something I could easily so myself. Thank you for having them on hand.

I recently bought a bridge doctor to sort out an old 60's epiphone acoustic, which had bellied and sunk near the soundhole. It was the first time I had tried one and it worked great. Much better now with no adverse effect to the tone. I have bought another one for a 50,s gibson LG0, which has the same problem. I highly recommend fitting one to rectify this or similar problems.

Great tool

I have redeemed my Fender 12 string and a six string Alvarez, both with the JLD Bridge Doctor brass pin mount system. I opted however to use only one brass pin and reinstalled the other original pins. I did not trust the brass pins with the nuts to stay tight and was afraid to tighten then enough to hold because the shaft was a good deal smaller than the holes for the original pins, letting the brass pins lean with the stress of tuning to pitch. I guess I'm just pickey that way but like things tight. As for the intonation and restoration to a perfectly FLATTOP, I couldn't be happier.

Good economical product. I used this to repair a bridge bow on a friend's Goya guitar. It pulled the majority of the bowing out and improved the guitar's tone. Though the guitar was an old beater I repaired it for sentimental reasons and I'm sure I extended the guitars life for another 5 to 10 years.

Be careful when counter sinking the screw mount hole to prevent cracking the bridge. I recommend this product and will use it again.

A truly great invention for the acoustic guitar. It gives the guitar added strength where they need it most and enhances the sound. A great bargain. I believe Breedlove guitars uses these on their guitars. A winner!
