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.

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.

This is the first time using the Bridge Doctor, and it wont be the last. I love the way it corrected the belly on the guitar and tone quality seems to actually improved. the only difficulty I had was the fact my hands were larger than the sound hole Lol. Improv at it's best.

Great on laminates 

By

I have now installed the bridge doctor (screw type) on three laminate guitars from the 70's and 80's. Two epiphones and a sigma.

In each case I would subjectively judge the sound to have improved by at least 2 points on a 0 to 10 scale. Maybe three.

I would say that it tightens up the midrange and eliminates that papery tone -- that sound like a paper speaker on an old cheap radio. The G string sounds much better, particularly

On an old epiphone jumbo I first overtightened the bridge doc and induced a buzz. Once I backed it down a little, it sounded great.

People are astonished at the tone I'm pulling out of cheap guitars I keep in my trunk and at work.

Worked for Me

Installed easily into old Japanese Conn w/decent belly and saddle-driven lowish action. Let it sit w/tension strings off X 2 days, then backed tension off and it stayed very flat, set normal tension (able to rotate dowel) and strung to tension - still flat, so all's well, except now that the bridge is pulled up to "normal," the action's almost high enough for a neck reset (out of saddle height). The belly was delaying the neck work on this new-to-me Conn. Note - do turn your drill by hand (no power) when cutting the 1/4" hole - needs just a few turns. I can see that using elec power will over-drill that hole.

Arrived early and was exactly as predicted. Instructions were helpful and easy to follow. Works as it was advertised.

It is easy to install. It absolutely removes the belly. It does, to my ear, brighten the tone and seems to increase the volume somewhat. That's just me though. Going to buy a few to have on hand at the shop.

Brought a bulge in an inexpensive Epiphone 12 string top down to help me get the action corrected.

Straight forward installation that did help bring the bulge down in a top.
