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.

Worked for Me

By
(Customer's Reviews)


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.

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.

Super upgrade

I have tested the JLD Bridge Doctor in various guitars, laminate & solid wood, and have ound that the Bridge Doctor not only takes out belly bulge but can also increase sustain and give most guitars a better overall sound.

I have a 1977 Yamaha FG 345 that had moderate bowing of the top. The Bridge Doctor includes very clear and easy to understand instructions. It was very simple to mount and install. I made my initial adjustment with the strings still removed and could see a noticeable lessening of the bowing. I let it sit overnight and made a second adjustment before stringing it up.

The string tension counteracted the device a little but subsequent adjustments at the next string changes should alleviate that. My action has improved and the guitar does seem to project a bit more loudly as some others have noted. I am impressed with the device. It is simple, easy to install and does exactly what it says it will. I would recommend this for guitars with mild to moderate bowing.

Tricky to install on a parlor but worth it

By

Does exactly what you expect, pulls the bridge back and flattens out a belly bulge, and means you can use higher tension strings on vintage guitars. I installed one in my 1927 Stromberg parlor. It was a little tricky because my hand only just fits through the sound hole and in the case of the Stromberg which has only one ladder brace under the bridge, I had to cut down the tube piece that the bolt screws into to get the right fit. Make sure it is tightly in place, or you will be removing it like I had to and making more adjustments. The benefits are these- stronger bridge, you can use heavier strings, intonation was fixed right away because the bridge no longer tilts forward, the sound is a big change however; tighter more defined, less boomy, precise and still warm, the guitar starts to feel like a real instrument now instead of a boomy resonant beast, highly recommended for every ladder braced parlor and MUCH cheaper than pulling the top to have an x brace installed, just find someone with small hands to fit it for you. If you are not DIY savvy I would let your guitar tech install it.

I bought the JLD Bridge Doctor actually because of a friends recommendation because I said I would probably throw the guitar away.
He told me you need to go onto Stewart MacDonald's and get the bridge doctor and that would take care of the problem because he did the same thing.
I never knew they sold something that would straighten up the bridge again and here it is.
