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.

Area 51 Technology?

I've been using the JLD bridge doctors for about ten years and they work great. I ordered my first bridge doctors directly from the Roswell, NM "inventor". It is such a leap forward for guitar repair it may lead one to speculate that this is recovered technology from the 1947 crash.

Happy playing! - Steve

Fantastic doo-hickey! Relatively easy to install, cheap, and permanent.

I've been using these things in my guitar repair for more than 10 years now and I can't praise them highly enough. They do everything the maker claims, and do it supremely well. You can try to flatten bulging guitar tops by replacing bridge plates, regluing bridges, etc. These repairs can be time-consuming and pricey and, because wood has "memory," these repairs almost always fail within a year or two, leaving you back where you started. The Bridge Doctor is an inexpensive and permanent repair, effective as long as you leave the BD in place. On most of the guitars I've used these on, there is a noticeable improvement in sound as well. Whether that's because the bridge is transferring energy to the sides and back via the BD, as the maker claims, or if it's because the top is flat again and operating at peak efficiency, I don't know. But either way, these things are a win-win.

Does what it promises

I put this on my Martin D12-20. This guitar has bellied in the past but relaxed after I let it set with no string pressure. Wanted to stabilize soundboard and bridge. Was fairly easy to install and I could see some improved flatness of top. Sound is not quite the same, but still very good - the only person who will notice is me. I like it.

I've installed three of these on relatively inexpensive guitars - two on six-strings after repairing split X-braces and one on a twelve-string and have had great luck with all three. My customers report that the guitars sound a LOT better with the tension from the strings removed from the sound board of their guitars.

Works well for flattening a top

I have been restoring a 60's 12 string acoustic that had been sorely neglected. The bulge behind the bridge was... significant. I humidified the guitar for a week prior to installing the Doctor. Installation was simple. Each day over the next week I did another quarter turn. Easy does it. After a week the top had flattened out and setting up the guitar became possible.

I cant speak to its effect on tone since the guitar was unplayed prior to installation, but I will say the guitar sounds great after restoration.

Saved a guitar that I was often told was unfixable

Really easy to install, and it does exactly what it says it does. The installation seems daunting at first, mainly because the paperwork that comes with it isn't quite detailed enough. But once you figure out how it's meant to function, it's pretty simple. The cheaper unit is identical to the more expensive one, except the expensive one comes with 6 brass pins. I bought both and ended up using the brass pin one because it requires no drilling. I imagine if you are good with tools (and cool with permanently altering your guitar) the cheaper model will suit you well. Personally, I don't mind spending a little extra to keep my guitar original. Also, the unit itself is quite small, and doesn't diminish the sound of the instrument one bit. The manufacturer claims it improves it.

Wish I'd done it sooner

The JLD bridge doctor was absolutely the right decision to reviving my late 70's Ibanez dreadnought. The guitar had bellied so badly that it was nearly impossible to play at concert pitch.
After installing the bridge doctor and adjusting the truss rod, the guitar is actually a joy to play.
I have a Fishman thinline installed under the saddle and the wire runs to the tail block and sits exactly where the torsion rod comes to rest. Once adjusted slightly off center everything came together beautifully. The complete job took about 40 minutes. This product greatly improved the value of my acoustic guitar.

Bridge Dr. does help support the bridge

I got this for my 30 year old Guild 12 string, which the finish right in front of the bridge was bubbling up from the stress. I followed the recommendation for 12 strings to use the deluxe version with brass pins. Installation was quite simple. I did read many reviews about installation, and read the instructions several times before attempting, as well as reading the on-line instructions which varied slightly. I had 2 problems. 1st was that the included dowel was just a little too short for my guitar. I emailed the manufacturer, and actually got a phone call within a day or 2. I solved the dilemma by going to my local hardware store and buying a long dowel for only $1.oo, and cut it to size. The second problem was the string holes in the pins are too small.
I had read that in several reviews, so I purposely bought extra light strings, but still ended up breaking one of the B strings while trying to get it through.
I replaced it with a new string, which I managed to get through OK.
The sound is very good, but I can't really say if it's any better than before. Time will tell if it helps the ripple in the finish.
All in all, I think it is a good device to have installed, especially in 12 strings that have so much tension.
