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.

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.

had to modify

Bought this knowing I'd have to modify it for a thin line acoustic electric. After modification it worked great at bringing the lifted bridge/should board back to level. Would definately suggest this as the first step to fixing a lifting bridge on an acoustic.

Required grinding or filing in order to clear the back brace and it dampened the tone of the guitar somewhat. I used it on my MARTIN 000C-16RGTE.

12 String

I installed this on a Gibson B45 12 String hoping it would stabilize the action. It's been through the four seasons in Chicago and it still plays beautifully. I've used it on several of my repairs with great results. John Devens

Easy to install and works as advertised.

I installed this in just minutes on a Takamine jumbo 12-string to correct a severely bellied sound board. The guitar sat in the corner doing nothing for several years because of unplayability and my not wanting to spend more than the instrument was worth to have a luthier work on it. The Bridge Doctor worked like a champ in minutes and I'm going to install one in my new Guild 12-string to prevent the same thing from happening in the future which is normal on 12-string acoustics.

I highly recommend using brad tip drill bits to prevent wander. Using a 1/4" brad tip on the bridge creates a nice center mark for the 9/64" hole for the screw. Measure carefully, work slowly and anyone handy with hand tools can have this in in less than 30 minutes.

Got it for a future project. After watching the video this might be what the Doctor ordered.

The product worked just terrific on my 1969 Gibson jubilee deluxe. It straightened out the sagging bridge back into alignment again. This happens after about 50 years of string pressure. Thanks for the product. Bryant Forehand
