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.

2 weeks in, and the old cheap Yamaha just keeps getting better.
I would copy the thing (it would take me about 45 minutes) but I am so happy with it, I want it's original maker to stay in business forever.
I will be buying more of these units to repair 2 other old guitars... an ovation 6 string, and an old Yamaha 12 string. Thank You JLD and Stew-Mac.

I installed this on an old Yamaha G-60A 6 string classical acoustic.
This instrument has a very narrow bridge, so the closest screw position just barely allowed for correct placement under the bridge. I was concerned the narrow fulcrum and the plywood top was going to be an issue requiring a lot of extra force on the pressure screw. This guitar also has a tall back rib below the bridge which required modification to the Bridge Doctor unit. 2 minutes on a disk grinder, and I nerfed a little bit off the bottom side of the unit, then was able to install it . The very small sound hole, and long reach to the bridge made for a difficult installation. Even so, in about 15 minutes (including re-tuning) I was playing it.

There was a huge improvement right away... the top is nearly flat already, the action is 25% lower at the 20th fret, and tone is already better. I can't wait to see how it seasons in over time.

Although this product is not particularly difficult to install, it does require some skill and experience as a wood worker. I am by no means a Luthier, but I have been working hardwoods into furniture for 40 years. If in doubt, have it installed by a professional.

Good fix

This works as offered. I had to trim the top of the bridge Dr. because the guitar was a thinner body than most acoustic guitars (Epiphone PR5) . But it fixed the problem and as others have said it does seem to be louder. I'm happy with the fix. I'l buy another to fix a 12 string I have on the bench.

I have installed more than 30 of these and I can't recommend them enough. In fact, I believe the bridge Dr should become standard equipment for all acoustic guitars! Preventative medicine is the best!!!

Works like a charm! A friend had a 12 string w terrible bridge belly. I ordered the regular version. The top is now flat and the guitar is louder than you’d believe.

Worked great.. instructions odd

This thing fixed my 40 year old Yamaha FG-200 like magic. However, I want to note that the instructions were written for two different products with weird confusion about what they were talking about when. Thankfully, the video instructions were good.

I bought this for a jumbo Takamine with belly-bloat, or whatever. It had great tone but was hard to play. When I figured out what was wrong I assumed it was going to be expensive to fix. Then someone suggested the bridge-doctor I researched it. Finally bought one and installed the screw thru bridge one. It was real easy to install and now my Takamine plays so good! Definitely worth every penny and saved a nice guitar.

Almost unbelievable!

First time with this, and I was a little skeptical. I was refurbishing a Penco 12 string made in Japan, it had the start of a lift on the bridge and a very distinctive "belly bulge" that I thought would not come out... It only took 15 minutes to install, only because I was being extra careful having never used this before... So easy to do and the results,WOW! I will make a good profit off of this guitar now and someone will get a fantastic guitar!
I am ordering a few more to have on hand!!!

JLD Bridge Doctor does what it claims

I bought a used Takamine EAN40c12 12 string guitar knowing it had issues with high action, belly bloat and a lifting bridge. I recall seeing a video where a luthier installed one on an old Yamaha. He seemed stunning it actually worked.

I ordered three of them as I have several acoustic guitars on their last legs. I had to decide which Bridge Doctor to get – since the Takamine EAN series has no bridge pins the choice was to get the lesser priced standard version. I also had to abandon the idea of counter synching the hole in the bridge to hide the screw with a MOP inlay – there just wasn’t enough room on that particular bridge without collapsing the holes for the 2 D strings.

I would also suggest drilling a guide hole through the bridge before drilling the 9/64th hole required for the screw

There was a lot more fiddling than expected to get it installed – but once I did – and I started screwing in the Allen Key – to hardly any resistance at all – I might add – first the lifting bridge issue vanished, then the belly bout vanished. I was very conservative on how many rotations I gave it – after putting the strings on (Elixer Extra light) and as always with my 12 string guitars – I tune them to D Natural – use a capo to 2 for E. The action was at 5/64th at the 12th – miles better than before. It now plays beautifully.

I bought the guitar for the equivalent of $420 USD (a steal) – with a $26 Investment in a Bridge Doctor – I have a 12 string that will remain solidly playable for decades. (there’s a reason you don’t see a lot of really old 12 string guitars around - they’re a bit of an engineering fail). The online chatter says it’s fine for low end and medium valued guitars, but I’d certainly use one on a Gibson or Martin if it would bring it back to life. The only criticism’s online appears to be those who put them in guitars that don’t need it – or some purist stance that you should never put a hole in an acoustic guitar.

The JLD Bridge Doctor has proved to be nothing short of a miracle for me. I’m kicking myself about the handful of beautiful old guitars I let go - that could have been rescued with this device.

Just what the Dr odered

What a great fix for a pesky problem with my Takamine.
I used this as a template to build another for my Epiphone that had the same issue with the bridge tipping slightly.
Easy install
Added more volume and tone.
