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 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: 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.

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.

A winner!

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!

It didn't fix this one

By

Verified Buyer


Sadly, the JLD Bridge System didn't fix my 1980 approx Yamaga FG 110. I am relatively experienced and gave the system every opportunity but it did not pull the top flat on this Yamaha. In the immediate short term it also killed the tone but I understand that when it works, this is supposed to improve. Like another reviewer, the long dowell fractured under torque and I had to replace it. Yes, judging by marks left under the bridge plate, the device is capable of applying considerable force to the underside of the bridge plate. All I am saying is, on this particular guitar, it didn't work and I lost a lot of time over it. Stewart Macdonald issued a full refund so full marks to them for their good customer service. I hope it works for you as it seems to for many of the reviewers here.

Great Fix

By

Verified Buyer


Every guitar is made different, so my installation was not as clean cut as expected. 4 Stars as I feel the plug could be thicker to accommodate curved bridges. Also, a model specifically made for shallow acoustics would be awesome. Trying to modify did not work as anticipated. Would not waste the efforts on a laminate guitar again, but then again, I found multiple other structural issues on the Yamaha I was repairing.

I have used several bridge doctors over the years and have had total success...I wished someone would design one that would fit the Ovation guitars! If there's already one out there, please let me know.
