## Overview

The JLD Acoustic Guitar Bridge Pins (#AN3694) feature an adjustable spruce pressure post that mounts beneath the guitar bridge via a screw, providing leverage to flatten soundboard bulges and improve bridge alignment. This precision device enhances sound projection, stabilizes action and intonation, and is designed for easy installation with included instructions. Ideal for vintage and 12-string guitars, it offers a cost-effective alternative to expensive luthier repairs while preserving your instrument’s tonal integrity.

## Description

The JLD Bridge Doctor 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 version: 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. NOTE: This tool requires a hole to be drilled through the bridge behind the pin holes. StewMac Tech Tip: We recommend the brass pin mount version (sold separately) for 12-string guitars. Installation instructions included.

Review: Worked Great. Saved $$$ - I recently put the Bridge Doctor in a 50 year old Martin D12-28 12-string that had been carelessly stored for the past 20 years and had developed a large belly bulge causing the bridge to tilt significantly toward the sound hole resulting poor action and poor intonation. This is a common problem with 12-strings due to the extra string tension on the soundboard. Some research which led me to two methods to correct belly bulge. The first was to remove the bridge and clamp two hot plates around the bridge area then wait - sounded like an expensive trip to a luthier. The other was the Bridge Doctor. The reviews were encouraging and installation looked to be pretty simple, so before taking the guitar to a luthier, I gave it a try. Although the brass pins version is recommended for 12-strings, I went with the screw version. I didn't like the look of the brass pins and was concerned about not having enough break angle - plus the brass pin version cost more than twice as much. Installation was easy. I used a screw driver type handle that accepted my drill bits, allowing me good control. After I'd cut the rod to length and made sure it contacted the tail block, I tightened it in with the Allen screw, being careful not to overtighten. I'd expected it would take some time for the soundboard and bridge to adjust, and would be followed by additional tightening. However, I was surprised to find that even after the initial installation, the bulk of the belly bulge was already gone and the bridge tilt was much improved. Over the next week, I have checked the tension on the Allen screw every couple days and found that I was able to give it 1/2 turn the first time, a 1/4 turn the 2nd, since then it's stayed about the same. I left it like that for a couple months to give it time to get used to the changes. The result? When I started, the belly bulge measured over 6mm - now it's about 1mm, about the same as my new D-18. The bridge tilt has leveled significantly, so that now the action and the intonation are much improved. Note that the Bridge Doctor will change the tone so that the top end loses brightness if it is too tight. So, after the belly was reduced and the top stabilized, I loosened the Bridge Doctor so it was just snug enough to keep the belly from coming back. This allowed the tone to regain most of its brightness. The Bridge Doctor saved me hundreds of dollars that I'd have had to pay a luthier to fix this guitar. I now have a guitar that plays great and saved a lot of money. What's not to like? Got an older 12-string that starting to show some belly bulge? Install Bridge Doctor, or take it to your luthier and have them install one for you. It'll remove the bulge you have and prevent it from coming back. One thing to note, the dot which was provided to go into the screw hole in the bridge is black, not abalone. This would have worked better for me anyway as all my bridge pins are black, but instead I made a wooden plug cut to an exact fit and stained it to match my rosewood bridge.
Review: Definitely a good purchase. - Easy to install and worked perfectly.

### ⭐⭐⭐⭐⭐ quality made invention that works like they claim!
*by B***E on June 4, 2025*

a great way to save a slightly sunken soundboard (top) I used it on a vintage MIJ Aria acoustic and it worked well. Just make sure you don't overtighten to hex rod as it could break. It doesn't take that much pressure too lift back up most tops.
