    awwww…you don't get to see it go back on?

    Part 2 will be uploaded soon.

    Fascinating. It's really nice to see someone taking their time, working carefully and doing a good job for a change. Nice work. I've just concluded that my 3-year old Dean has dreadful belly bulge now, and the sound is poor too, so this is very interesting to watch.

    Thank you, I will have part three uploaded sometime tomorrow, in it I finish off this repair by installing a JDL bridge truss system. It not only will help fix a bellied top but will improve volume, tone and sustain of your guitar!

    All three videos are very good, Great job and very informative!!

    GREAT video!! I just purchased a LAG of eBay and, of course, the seller neglected to mention that the bridge had separated from the body. I was bummed because it's a REALLY nice guitar otherwise. But now, I I think I can fix this myself thanks to your bid so THANKS FOR POSTING!!

    You must have the same tooth split I do…I notice he whistle. 
    I have no belly bulge, at least on the guitar, but I do have some humidity lift cracks in the facing behind the bridge. Any ideas on how to get rid of them?

    This is a truly amazing video,, Scott — I enjoyed watching you work on this poor guitar. So nice to see damaged guitars being saved.

    Super glue is bad for guitars! I've heard so many bad stories about it from my luthier.

    Thank You Scott for this series of videos covering this type of guitar repairs..I just purchased an Aria guitar for the grandson, it had one broken string so I would restring it when I got home, I discover that it has 4 broken tuners and a swelled belly. Since I have retired I've been buying some tools from Stewmac so I can tinkerer on the guitar I have. I've learned a lot from videos like yours on You Tube. You made a statement that some guitar belly swell in normal would you expand on that a bit? and did the JLD bridge doctor work on a belly swell beyond the bridge?

    We got about a buck twenty of bulge here.

    The peizo can be removed first as the wire goes straight through. Very interesting video.

    I call the bridge doctor, the tone eliminator block.

    What is the name of that tool that you use on the hotplate to heat up the glue under the bridge?

  • Reply Shoeless Sean McCulloch January 26, 2016 at 11:11 pm

    Scott, awesome video! Can you post a list of all the tools you used, and where to buy them from?

  • Reply Victor Jones January 27, 2016 at 1:03 am

    this is fake you cant heat up the bridge and flatten the belly bulge wouldn't the heat loosen the the braces around the heat
    and the bracing isn't clamped so things would become loose in there
    and why would you then add a JDL bridge truss rod system
    is that in case the belly collapses

  • Reply indcsion May 15, 2016 at 4:10 pm

    What would u pay for one of these guitars that needs repairs? The one I'm looking at is missing the tuning pegs, bridge, truss rod cover, nut and saddle, and it has crack on side.

    Thanks Scott for taking the time to share your experience with acoustic bridge repair techniques. I've a 12 string whose bridge lifted while I was tuning and I needed to see something like this video before rolling up my sleeves and giving it a try.

    good night, this piece after it is installed, gives difference in the sound of the instrument?

  • Reply Jerry King October 4, 2016 at 6:21 am

    I just put a JDL guitar Doctor (the one where a hole is drilled) on an old Fender 12 string someone gave me… New strings= it sounds like a HARP!!! Very pleased with the results and sound…

    Scott – did I miss the part where you fixed the bulge?

  • Reply EasyAzPiE October 24, 2017 at 8:14 pm

    what type of glue do you use to glue the bridge down?

  • Reply Roger Rainville November 25, 2017 at 12:24 am

    Hi.
    what is the proper temp. and his much buldge is acceptable?

  • Reply Anthony Monaghan May 17, 2018 at 6:41 am

    I'm wondering how I would do this on a classical guitar where the bridge has a finish on it. In other words it's not bare wood. A hot iron is going to melt off and damage the finish. Any ideas? Cover the bridge? I need to take the bridge of to reduce the string height as there is no truss rod. It's a 1975 Kiso Suzuki. Cheers.

  • Reply george scarlett November 17, 2018 at 7:11 pm

    I just de-solder the pickup wire, or some are just held by screws, or spring contact, then you don't have to either worry, or fuss with the pup wire.

  • Reply JoJo Bar December 28, 2018 at 10:20 pm

    Good job! I wonder if it would help to dip the flat wedge into boiling water every couple minutes.

  • Reply Jack Castaneda January 1, 2019 at 1:16 pm

    Would a hair dryer be a good alternative to the bridge heater?

    You can say many about Epiphone, but for sure they glue bridges with passion

  • Reply Mathews Triax January 26, 2019 at 5:02 am

    Only way to fix is a neck set and re glue the bridge.

    Great vid…..

    I take 2 pcs. of wall lath and measure over the bridge past the end of the guitar. I drill 2 holes on the ends. I buy a long threaded rod and cut it to depth size. I attach wing nuts (4) at each end of the rod. Turn the wing nuts and snug it up so it looks even or balanced. I take a plastic coffee can lid, fold it and put it inside the guitar. I get a wet sponge but not so much as it drips but as wet as it can be and I place it on the plastic lid and slide it under the bridge area inside. After a day, I snug each wing nut a little but not very much. In the evening I check the snugness and turn it again putting slight pressure. It's important not to go too fast. The next day I snug a little more and the same that evening. In time the belly will be coming down and I' check the sponge daily to make certain it's moist. If you have a hydrometer to place inside the guitar, I would check it but not let it go over 40. I keep repeating the process until the belly looks flat. I take an aluminum straight edge to check for bulging. When it is perfect I start releasing the pressure a little at a time with the wing nuts. If it starts to bulge again I snug it back and keep the sponge semi moist and when it drys I check it again. When I'm confident the bulge isn't coming back, I let it lay a few days. So, this will take care of the bulge. Most of a bulge comes from the top sinking in front of the bridge causing the bulge to lift.

    I thought you said you were going to show how to fix the Belly Bow

  • Reply theID2 May 27, 2019 at 1:48 pm

    way too much time in pointing out details. for instance … you showed the inside bridgeplate, which was obvious, and then moving the camera around showed it again identifying it again as the bridgeplate with a closeup. same with the bump etc. you do this all over this video and it's tiring! almost 15 minutes for this and it could have been shown in less than 10.

    Wouldnt some acetone help with the superglue on the wire?

  • Reply sealand000 June 30, 2019 at 1:29 am

    Belly bulge is a result of the owner not giving the guitar enough of a workout.
