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.

Great for Family Guitars

(Customer's Reviews)

I bought this to fix a family guitar that needed the belly fixed. This product works great.


My 12 string, strings were getting so far I could not play it.

(Customer's Reviews)

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.


Love this product

(Customer's Reviews)

I put it into my Masterbilt that is only a little over a year old. Even with keeping it humidified and in the proper temperature range it was beginning to belly up. It had also lost some of its beautiful tone. I installed the Bridge Doctor. Took me about 2 hours but I was being very careful, and meticulous. It took the belly out and re-leveled the bridge. With in a couple of days the beautiful tone returned to my guitar. I think once the stresses are removed from the spruce top it really allows it to vibrate as it should. I could not be happier. If I ever get another acoustic guitar I will put a bridge doctor in it first thing.
