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.

Takamine F385 12 String

(Customer's Reviews)

I own a Breedlove Solo Concert and it has a very similar unit in it as the JLD Bridge System. I used the pin mount version #3695. I spent two weeks slowly humidifying the guitar in a hardshell case without strings on it before installing the bridge system. Once installed I spent two days making small adjustments before restringing. It's not a "fix all" as my action now has to be readjusted but my 34 year old guitar is once again playable and well within the realm of fixable with minor adjustments to the bridge and nut.


It really works!

(Customer's Reviews)

Finally got around to installing this on my Cat's Eyes (Tokai) acoustic. It worked wonderfully. Easy to install and adjust, and it took the belly right out of my guitar. I even like the look of the screw head coming through the bridge--it looks utilitarian.


Mixed Results

(Customer's Reviews)

I installed the no-drill version in my 1970s Aria 12 string and I am delighted with the results - maybe not quite the same tone but certainly worthwhile fixing the belly.

I then installed a drill version in my 1969 Yamaha G170A ( gold label ) classical- the feature bright tone has been destroyed and volume down by 5 - 10 db. It was very tedious to install as it was too large had to be shortened and had to cut groove for the centre brace. On this guitar all up a waste of time and money.

I suggest JLD consider a classical version
