Your cart is empty.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. Brass pin mount version: 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). 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. StewMac Tech Tip: We recommend the brass pin mount version for 12-string guitars. Installation instructions included.

Overall really easy to install, and look amazing especially on my Takamine GD37 Pearl White 12 String, but the only issues I have is the whole sizes vary, and although the string fits, when it reaches the end it struggles to go through and I’ve had to do a slight modification to my strings to make them fit again. I didn’t have a problem with belly bulge to begin with, this was just a preventative measure since I use two sets of extra light (10-47) strings instead of the regular strings. Anyone who plays regional Mexican or uses double 10-47’s I recommend this, but just be aware that in some occasions the pins do not come with the same size hole.

This does what it says it does--but it took some work to get it installed. If you use strings that are not light gauge you may need to open up the holes in the replacement bridge pins to allow the ball-ends to sit properly. I found it helpful to dry-fit it in both available positions because of the fairly narrow bridge plate. Once installed and strung it worked as advertised. I did not attempt to flatten the top completely, just turned it a half turn past initial contact and let it sit for a few days. Like tightening a truss rod it continued to improve over time. I am very happy with the results--reflections in the top show very little distortion and are nearly uniform across the entire surface.After a month, I am even more impressed by the JLD Bridge Doctor. I have not adjusted it since I wrote the review above, but the soundboard has continued to flatten to the point that there is almost no trace of warping above or below the bridge--reflections are almost perfect everywhere on the soundboard (I hang it near a window with Levelor blinds and have watched the reflection change from wavy to perfectly straight parallel lines). As a result the neck angle has changed so that the action is much too low all the way from the first to the 12th fret. I now need to make a new saddle that is almost 3mm taller (25.6" scale). This device is worth it's weight in gold--it did the job of a neck reset and fret leveling for less than $100.

This product just works. Beautifully!I installed this on my wife's vintage 1966 Gibson B-25. Her father bought it for her new at that time.The guitar was unused for many years and when I inspected it found a dip between the sound hole and bulge below the bridge.Found this device and decided to go for the brass pin model because I didn't want to drill a hole in the guitar. Well it arrived a couple days ago and realized its a good thing I got the brass pin model because there isn't enough room on the bridge to drill a hole.Well this went right on, took about 30 minutes. Once installed, I just tightened the set screw and like magic the top flattened out. Strung it up and it sounded pretty good, I figured it needed some time to settle so the next day, I played it a little, sounded good but not great with silk/brass strings.Decided to put some 80/20 Brass strings on it to brighten things up. After getting the old strings off, I found a couple of the brass pins a bit loose, especially the low E. Well, I tightened everything up, straightened out the alignment of a couple and lowered the saddle a bit. Well after I got everything back together and played this thin I was shocked at the beautiful sounds that were coming from this thing.I understand it may take a few weeks for the guitar to really settle in and reach its final destination but right now 2 days in I am amazed at the quality of the sound.The action is still a bit high for me, not much and because of the pin height and how the string breaks over the saddle at a low angle, I will need to contemplate a final solution but its a minor issue as I only need to lower the action about 1/2 mm.I was ready to spend up to $500 to have this fixed by a luthier but now I think this is a better solution because it is a permanant fix. I highly recommend this product.
