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.

Acceptable and easy fix.

It works but does leave somewhat amateurish evidence that it is there. If you don't mind a fill-hole in your bridgd, (they supply an abalone dot) and it being visible through the sound hole, it is good, but if you cherish some ancient model that must be preserved at all costs, get a neck reset.

these are great for guitars that have a slight belly bulge and not only are they a quick and easy assembly they'll enhance the tone as well, making the tone much sweeter for the player.

Easy fix for a difficult problem. The Bridge Doctor works extremely well at straightening up a bridge and soundboard. We've saved many guitars using this simple device. Especially useful on 12 string acoustics that are notorious for bellying a soundboard. These are a staple in our shop!

what an amazing product!

I installed this on a friend's Johnson acoustic that had an extreme belly surrounding the bridge. The installation was quick and easy enough to accomplish in less than an hour... What an amazing change to the guitar: the belly was flattened with a minimum of tension applied AND the volume of the strung guitar seems to be positively increased. Wow!!!

I have a 30 year old Martin D16 that has been through the wars - too many canoe trips, too many camp-fires and one disastrous plane trip to Honduras. Plus it was on the prairies (Alberta Canada) for 25 of those years so it got very dry and you could get the corner of a sheet of paper under the bridge at one place.

I took it in to the local guitar store to see if the luthiers could do anything to restore it but they were afraid it would fall apart on them and sent it home for palliative care. The thing still plays like a dream - I love it, so I thought I'd try the bridge system ( the screw mount version).

The one wrinkle is I have a Fishman pickup in it and of course the middle transducer is right below the bridge where the post goes so I had to notch out about a 9/16 gap in the top of the post leaving barely more than an 1/8th of an inch on each side of the transducer to brace against the bridge block. I just followed the recommendation to just tighten slightly beyond the point where you can freely turn the dowel. There are a couple of very good videos on YouTube showing installation - can't figure why the manufacturer wouldn't post one but anyway ...

It worked like a dream - no ill effect on the pickup and seems to have solved the bridge problem and improved the sound a little (hard to judge on that front but it certainly hasn't been detrimental.) Fairly easy to install if you use care. Definitely recommend it

Installed it in a Picador acoustic that had a big belly after re-attaching the pulled up bridge. Huge improvement in tone and action. I also recently got a chance to use my Saf-T-Planer to thickness Texas Mesquite wood for a new type of acoustic guitar. Worked good.

My Gibson Hummingbird had some belly-bulge issue and because of the bridge type it has, I had to get the JLD version with bridge pins. BE AWARE that the strings don't all fit through the brass pins. I use Cleartone 11-52 and had to drill out the top E and A using a 3/32 bit. Installation was not too bad. You'll need a few more items than directed but if you routinely maintain your own instruments, you'll be fine. The results were impressive, bulge is almost entirely gone. They say it improves the sound but I have not "yet" noticed any improvement. However my Gibson sounded great as is and NONE of the tone was lost. I would certainly by this product again if needed.

I ordered this item to fix a belly warp on an Aria 12-string guitar and though the instructions were not explicit enough I am still pleased with the results, so let me star with the Pros first.
Pros: It is a quick solution to avoid complex ungluing and dissasembly of your guitar and it relatively fixes the problem. Now, it didn' t quite fully fix the warping around the rosette of my guitar but that may be due to a different problem. In sum, it helped ro reinforce the bridge so the warping on the belly and the rosette did recede substantially. Cons: The instructions aren't clear enough so you can't tell the difference between installing it on a 6-string vs. a 12-string guitar! I thought at first that my kit was short of a nut and the retaining screw so I went to a specialized store to buy those items. I preferred to buy the items 'cause I didn't want to wait another two weeks or less for the missing components, but after studying the drawings on the instructions carefully, plus interpreting the text on the provided instructions many times I came to the conclusion that there were no missing screws or nuts. All I had to do is put one of the supplied pins through the lower D hole on the bridge and use that as the pass-through-screw to retain the JDL Bridge Doctor beneath. I did sort the pins according to the diameter of the holes on its heads first(Very important step) . I also had to saw off a half-inch piece from the provided wooden dowel to shorten it enough to fit this guitar in particular. Ant that was it! I re-strung it and gave it a go!
All in all I am pleased with this solution and would have given it 5 stars if not for theinformational gap on the instructions that made me to re-interpret the text to obtain the desired results. Last, I would recommend with this or any other item to take your time and read and study the instructions and diagrams thoroughly to avoid any mistakes while installing.
