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 tail block, 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 tail block, 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.

Incredible invention!

By

Verified Buyer


Put this on an old Fender F-35 that was left to me. I scalloped the braces a little too much and the top warped. BUT the Bridge Doctor fixed it. I sounds as good as my Martin now! If they made a neck Doctor so it would play as well ....probably not, but I keep this guitar on a stand so I can pick it up for practice. Incredible sounding guitar now, thanks to the bridge dr.

Bridge doctor

I love the bridge doctor as a fix to Acoustic bridge problems. I have installed 6 or more now and have had excellent success with the results. I ran into my first time problem with an output jack being in the end of the guitar. I have seen another review stating this problem and suggesting cutting down the post and fulcrum block. I cut a 1/2" off to make it miss the output jack, I feel like this reduced the leverage too much. I would like to see a bridge doctor with a 1/2" longer nylon pin and wood fulcrum block. "Oversize Bridge Doctor" keep the great parts coming.

First Rate Invention-Highly Recommended

I've used the Bridge Doctor System (without brass pins) on numerous acoustic projects, including nylon and steel string guitars, and have found them to be a brilliant solution to bellied tops. A few of these jobs have required pre-treatment with the Thompson Belly Reducer if the warping is so bad that the bridge has started to lift; sometimes a couple of treatments are needed while the bridge is off. Once the bridge is on and the adhesive has cured it's very easy to install the brace and get the guitar top back to level again. There is always an improvement in tone and sustain as well. Stewmac's price is far better than what I've found with suppliers in Australia.

JLD Bridge Doctor does exactly what it says it will

I have Fender 12 string made in Korea. The bridge was being pulled down toward the sound hole with the accompanying belly bulge. I installed the Bridge Doctor after I had flattened the belly between two pieces of oak with clamps. Once I released the clamps I gave the tension set screw another turn before restringing. I had an issue with the brass pins sinking into the tapered pin holes making it hard to get the strings through them. I ordered some brass washers to put under the pins and they solved that issue perfectly. I restringed the guitar and it looks like new now. The bridge sits flat and there is no belly. It plays perfectly. The bridge doctor brought a guitar back to life. The guitar was not worth enough to get a professional to repair it, but it was definitely worth taking a shot with the bridge doctor. It was easy to install and adjust. I would recommend it for anyone needing to correct a bulging belly on their guitar.

Did not work for me

By

Verified Buyer


I bought this to fix a belly bulge that was creating a very high action on my Mitchell MD-100CE dread. It was a last ditch effort to fix while not spending a lot of money. I think that it did not work for me because the guitar has been like that for a while and I believe it's a laminated top. I tried the middle setting and the outside setting but no matter how much I cranked it the bulge never budged. The saddle remained at a downward angle toward the sound hole.

I know it can work since I saw proof in a few videos but it just didn't work for me.

Great fix for guitar tops!

By

I bought this for a vintage dove copy with a severely sunken top. I installed the bridge doctor in about 15 min with no trouble at all. Did initial adjustments, waited 24 hrs and tightened the adjustment slightly. The top is just about perfect. The guitar went from unplayable to enjoyable in no time. I highly recommend this!

Be sure to do your homework, but great for it's purpose

First thing be sure your guitar will accomidate it. Some bridges have bracing that prevents the device from fitting. I used it on a 25 year old Takamine C132 Classical guitar which required shaving a center brace that goes along the top from soundhole to tail block, then the center back brace was too tall so i cut 1/4 inch off the bridge dr. after that it was pretty much per instructions.
A classical bridge is so narrow you need to make a new hole to bring the attachment screww into allignment. Restored the intonation, and tightened up the top which sounds more spruce than cedar now. I am going to try the screw version a very dilapidated Martin D35-12 next. I also build a clamp to level the top before cranking down on the adjustment rod. After two months it still retains its position. Do some extra hydrating for a week or two before and after.

Excellent product, helpful instructions

I chose JLD Bridge Doctor, screw mount version, to flatten the top and hopefully improve the tone of an old, inexpensive Kay Model K-509. This guitar is worth under $100, but it's already paid-for and the value matches my skill level.

I know the Bridge Doctor improved the structure, because I can measure the flattening, down to very slight curve (about .1 inch sagitta for geometry lovers).

I believe Bridge Doctor helped the tone. This particular model K-509 has an adjustable bridge, which supposedly weakens the tone. The Bridge Doctor creates a solid link between the bridge and the tailpiece brace, tone seems louder, more even from one string to another.

A tip -- using a 3/16 hex head on a u-joint socket on an extension with a thumbwheel ratchet, I can adjust the screw in the Bridge Doctor after reinstalling the strings. Photo attached, but if you know tools, you'll understand even without a photo.

The StewMac site provides helpful installation pictures and video... plus lots of other interesting products that I will explore further!

Bottom line -- The JLD Bridge Doctor did not fix every shortcoming of a cheap guitar, but it's an inexpensive add-on that made a cheap guitar better.

I have installed these on a number of guitars, to reduce/ prevent bellying, and correct the saddle/bridge angle ( including one of my precious 1960s 12-string). Because they take tension off the soundboard, among other tings, tone invariably improves. - P.D. Wilson Stringed Instrument Care
