Details

• 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.

Disappointing results

By Christopher Moyse from HORSHAM UK 
(Customer's Reviews) Friday, September 19, 2014


I had great hopes that this would fix the belly on my 24-year old Lakewood (great sound, but a pig to play!). It had no appreciable effect on the belly, although it did affect the tone - not better or worse, just different. Having studied it closely now, I fail to see how this device could ever fix anything other than an almost imperceptible belly. My Mileage Varied, I guess!

I though it would be a monumental task repairing the bridge from lifting on a inexpensive Japanese Aria guitar. This is stupendous news that something so simple as the Bridge Doctor can fix the soundboard. As far as tone it reduce some bass but increase the intonation/sustain/ vibration whatever you call it. This baby, it works! Thanks Stewmac you guys have a top class staff that answer all my questions knowing that I'm not a guitar luthier and everything I've order was packaged and sent just as it was ordered!

Simply great device

The Bridge Doctor took an old, cheap guitar with severe bellying and made it playable again. About 20 minutes invested in the install. By the way, all the hype about improved tone is for real. I've ordered a Bridge doc for a vintage fender. I would use the Brass Pin mount on the Fender but somebody already butchered it some years back.

brilliant solution

Had a recurring top bulge problem behind the bridge on an extremely lightly built single O. Tried several heat/steam fixes but the problem kept coming back. The Bridge Doctor solved the problem brilliantly and improved the tone of the guitar noticeably. Fitting the drilled hole behind the bridge pins was a bit tight with the traditional pyramid bridge, but I put in an abalone plug instead of the plastic one provided and it looks great. Had to grind down the bridge pins nearest the mounting screw to fit them around the wood block, but I probably could have taken it out and knocked off the corners of the unit instead. Highly recommended. Don't be afraid of this fix.

It's great....I THINK

Ordered this after doing a lot of research and the verdict seemed that it helped guitars with 'pulled forward' bridges. I bought it to rejuvenate a 30 year old Eko 12-string belonging to a friend. I was nervous fitting it (I had to drill out one of 3 rivets securing the Eko bridge in place) but it worked out fine. TIP: Draw your guitar bridge out first on paper using accurate measurements to 'test run' this thing before you go ahead and fit - and so you can get an idea of how it works. I did and it helped a lot to reassure me what was going on. Result? I *think* it has stopped the buckling on the 12 string; I've lowered the action (made a fresh bridge saddle piece) and it's playable once again. Did it fix the buckling? It's hard to tell... I think it did a little bit. I believe it has certainly stopped it going any further under the massive load of the 12 strings. Time will tell: I've asked my friend to bring the guitar back to me in 3 months time to take another look. Overall, I think it's well worth doing.

Bridge Doc

By Pupster from Puyallup, WA
(Customer's Reviews) Friday, February 21, 2014


Much has been said in favor of the Bridge Doctor but I wanted to put some emphasis on how easy the thing is to use! I installed a "screw mount" on my "late '67-ish" Yamaha 12 string and found that working slowly/carefully rendered superior results. The one instance where I varied from the written instructions was in the use of a variable speed screwdriver, a hardened steel drill bushing/guide and a stop collar to drill the relief for the "button".

Great solution for a 12-string

By Hipabilly from Bowling Green, KY

I have an inexpensive Oscar Schmidt 12-string that always played well and had good action, but the action was starting to get too high. Bridge Doctor was the solution. I used the single screw, which worked fine with my bridge. It had enough adjusting options to position it correctly under the saddle and still allow room for the original pins (see photo). Easy to install. Great product.

Not exactly worth $50

I ordered the brass pin mount and put it in my Grandfather's 12-string... This guitar was badly warped with about 1 to 1 1/2" (maybe even 2"... I didn't measure.) gap between the neck and strings @ the 12 fret. It is tightened as far as it can with no movement of the top. There is only 2 stars for the fact that it was complete and i had no issues installing.

Nice

I could go on about this thing but it's all been said. Installed the screw mount in my 40 year old Hummingbird copy. I R & R'd the bridge as well. Only one problem .. had to shave 3mm off the bottom to make it fit but what an awesome response to all issues. Great product.

It saved my baby

It saved my old Epiphone flat top. Before this, the bridge would pull up and the action got quite high. No problem now
