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.

Favorite Fix for Bellying Guitars

By

Verified Buyer


You know the problem, you get an awesome guitar with great action, and sounds just like you want it. yikes, the bridge has started pulling up and its bringing the wood from the top up with it. Its called bellying. To the rescue - Stew Mac has this awesome product called the Bridge Doctor. A simple installation to bring the bridge back into alignment with the top and carefully bringing the top back down to flatness. I have used this fix on both newer and vintage instruments with great success. I have installed it in at least a dozen of my guitars. Got a Belly problem? No, not your waistline...grab one of these to fix your guitar...the other problem you are on your own to fix. Lawman-Mike

Worked like a charm!!

By

Verified Buyer


While waiting for snail mail I removed the strings off the guitar and carefully weighted the bridge. In the span of a week this dropped the bow by about 1/16". Doesn't sound like much but it was very noticeable.

The install of the JLD system was very easy. I read other reviews of people snapping the tension rods and such.... This system is based on fulcrum points and leverage... You do not need to 'crank' anything. Your are given three adjustments on the wood block before installing it... Go with the widest one that works with your guitar bridge and bracing as this spreads the load (better leverage) under the bridge. When I installed the dowel I purposely set it at a downward angle towards the back of the guitar for even more leverage... It has worked great. Action is perfect and I am playing this guitar again... I was about to make fire wood out of it.

A few smarts and some planning go a long way here. Think it through... It does work great. I will buy a few more just have on hand.

Good design, but didn't work for me

By

My guess is my guitar had a little more bulge at the bridge than this product was designed to fix. So now I have the item installed and the bridge is still too high to make the guitar playable. If you consider the bulge you're trying to fix as big or extreme I wouldn't purchase this item. If it's small I'm sure the device will pull the bridge & top down to flat and you'll be pleased.

Just installed JLD Bridge DR. on my ancient Yamaha Red Label FG-180. Easy as pie. With the new Grover Tuners, Bone Saddle and Bridge Dr. it sounds wonderful. As nice as my Martin.

Brilliant Invention!

I have used these devices in several seriously bellied instruments and even saved a destroyed 1952 Martin 0-18 with one. Assuming the end user is knowledgeable in the art of guitar repair, you can work miracles with one these.

This saved my 12-string 

By

Verified Buyer


My '73 Ibanez "Hummingbird" 12 string had a soundboard like a globe and was unplayable, but the bridge doctor saved it. The instructions could have been a little clearer, cause I ended taking the whole thing apart just to put it together again, using the back row of string holes. First I was disappointed, but after 2-3 days the soundboard had become flat and like new again.

Great if you know what you're doing

Good product. Is not a fix all device but it does its job well and it will frustrate those with little experience. Helps bellying and it does increase volume if installed properly, it makes cheap acoustics sound much better. Like a truss rod for the top.

Not For Weissenborn...

By

Verified Buyer


I bought one of these kits to help with the belly on a Weissenborn clone. Not nearly enough clearance within the body, so check the clearance on your application. I also found the holes drilled through the brass pins for the unwound strings way too small, at least for the strings I had on hand. Altogether not a very successful project for me.

beware

This is not a drop in item where one size fits all. I had a lot of problems & had to replace the dowel rod also.If your bridge pins are not in a straight line it starts there.Mine are in a semi-curve & the bridge is also set in on an angle.Both E strings are real close to the bridge & it is not possible to get the low E through the hole in the pin & over the bridge where it is tied off without enlongating the hole.Also,depending on the type of strings you use you may have a problem getting them thru the holes at the ball end where the wrap is bigger.I did & had to open up 2 of them.It has taken a lot of tweaking to get it to work because I actually lost sound when first installed & quite frankly I got sick of screwing around with it.I would never install another one.I'm not saying it don't work good for others, but the design of the guitar plays a big part of that.If you ain't good with handtools & don't have a boatload of patience,get a repair person to put one in if you think you need it.Like I said,buyer beware !

2nd installation - astounded me again!

By

Verified Buyer


After recently installing the Doctor on a Washburn, when I received an old IBZ concord 12 string with a cracked/lifted bridge and belly, I knew exactly what I needed to do. Once again, immediately after restringing, I was very nervous as I could not get a decent action . . I let everything settle for 2 days, and when I checked again, it had the slickest action I've ever seen on a 12! Be patient and let the magic work itself! Already have client requests for another 2 installations!
