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.

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!

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.

Easy and effective

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

Handy device

By

Verified Buyer


This worked as well as described. There were a couple of issues that I had to resolve on my own. 1) the directions don't mention that when you mark the dowel to cut it, you have to cut an extra 1/4" off to insert the screw. 2) If you have a pickup jack replacing your strap pin, you'll need to chop off a half inch of the top of device or add to it.

Great problem solver

By

I built a herringbone dreadnought about 6 years ago which turned out really well and put it in its case along with all the others. As I just build as a hobby and don't play very well, I don't see them very often. I took this one out of its case a few weeks ago and was blown away by the belly behind and the dip in front of the bridge. I put an inspection mirror inside and saw nothing had let go or broken and even the lacquer down the centre line had not cracked, I immediately took the tension off the strings. I bought one of these JLD bridge doctors and installed it. It fixed the problem perfectly before any damage occured. I highly recommend them.

Works as advertised!

It lessened the belly in the soundboard of a guitar that I picked up second hand, that also hadn't been cared for too well. As for the sound, it turned a $100 Ibanez into something that sounds much more expensive. I'm probably getting another for my lower-end Breedlove.
