    Update: I used your method and it corrected the back bow. I heated the neck for 10 hours straight. As the neck heated up I constantly tightened the strings when they started to lose tension. I also gently applied pressure on the neck by hand every hour or so. The results were stunning.
    Thanks a bunch for this video. It saved my guitar from the trash heap. I can string the guitar with 9's now and have relief to spare.

      Great instruction! If it hasn't been said, I thought about putting a metal riser nut (like for Hawaiian/Raised string slide style conversion) over the existing nut. This would keep the larger wound strings from cutting into smaller string slots. The additional temporary nut height may help with the pulling tension as well. Have you had success with one piece maple Fender necks, with the walnut filler strip in the backside?

    I just have to add to all the success stories here over the last 4 yrs. I am building a partscaster (Jazzmaster style) guitar. The body came from somewhere in Europe, and the neck is a licensed All Parts neck. They both however then traveled to Northern Ireland for a Nitro aged finish and nut/fretwork session before they were then sent all the way to Boulder Colorado - which is super arid at almsot 6000 feet. Thus, I fault no one on the fact that by the time I got this neck it had a back bow of about 1/16th of an inch with the truss rod completely loose. I followed the video, and wrapped the neck in a heating pad that maintained 150 degrees measured with a meat thermometer at the wood. I used 46/36/26-26/36/46 and took the E's up 2 steps to start and matched the tension by just tuning to the 5th fret on the other two notes. Total time wrapped and heated over three days (same deal as the video I had to reset every 2 hours with the auto shut-off) was about 20 - 22 hours. I readjusted the string tension 2 times a day. Finally after the 3 days of heat, I let it sit for another 5 days at room temp under tension. I just got finished with the final set up, using 10-46 strings, .006 relief, and my preferred med-low action 1.5mm low E and 1.25 high E - it set up perfectly with the truss rod just barley engaged. I will say I had no issues at all with the nitro on the neck at that temp. It did however hasten fret sprout. This is not a problem for me as it happens to every single guitar I’ve had that lives in these weather conditions, if anything it was a benefit for me to just get it over with now - but be aware this may happen, or be surprised if you are not used to it. Thanks again I learned a great deal with this problem and solution!

    Another success story to report. This was an inexpensive Squier Contemporary (left handed...my choices are limited). With the truss rod completely loose strings in tune, the neck was dead flat with a slight back bow around the second and third fret so the first and second frets buzzed badly.
    This is a solid maple neck and fretboard (with skunk stripe), which Iot of people suggest in other places is not repairable, claiming application of heat causes the fretboard to reseat on the neck.
    I bought an $18 heating pad (12x14) without auto shutoff on Amazon. With the cover off, I slid it under the strings (EADDAE), wrapped it around the neck and strapped it down with a long Velcro strap. I replaced the trem springs with five extra stiff springs to deck the bridge under the extra tension. And I tightened the heck of the strings.
    I heated for 30 hours and cooled for about 24. I strung it up with 10s and got enough relief that I could probably add a touch of truss rod.
    Success with a maple neck!

    THANK YOU! I've spent my entire practice time for the last 2 days trying to increase the relief on my Epiphone LP Custom Adam Jones Signature (Veil of Bees if anyone is wondering which one). I thought I was going to have to take it in to the shop to get it fixed or return it if I couldn't get it fixed. I reached the point where it felt like it was about to be so loose the screw/bolt or whatever the heck is in there was going to come out completely so I was scared that was going to be a serious problem. I have searched google, TH-cam, Epiphone website, etc. and your video is the first one I've seen that mentioned it might be a dual action rod and to keep loosening cause it'll grab tension again. I'm so relieved but honestly a little embarrassed and mad at myself for wasting all my practice time! So, again, thank you very much!

    Nice video and great info and great idea w/the heating pad!.
    I am an electric player, but recently was given an acoustic guitar that is back-bowed from about the 5th fret to the nut. I could barely turn the truss rod nut a 1/16th of a turn to loosen it, and did not want to force it...(This truss rod nut is at the head stock on this acoustic), so hoping by de-tuning the strings to release the back tension on the neck will work.
    If the nut is still stuck (or extremely hard to turn where you might break/strip it), are there any lubricants that can be sprayed in there to help loosen the nut up?
    Thanks and very well done video. Giving you a sub for a great idea w/heating the neck.

I find out after the return period was over that my friend told me the neck was so severely back bowed that it would have to be removed to be straightened.

      It will work in any situation without damaging any guitar. This process only applies to a "back bow" where you are not getting enough relief on the neck. If you have a neck with too much relief then you would have to make a clamp to pull it back the other way. This guy is one of the BEST builders on TH-cam and he has an excellent video addressing this method (Freddy Gabrsek) th-cam.com/video/1v5i8sEJ2LQ/w-d-xo.html Hope this helps and thanks for the sub!

    Anyways good idea the heat belt, coz you can't find those specialized fretboard heaters anymore (well not in my country anyways).

    String tension will add the relief needed; that is how single-action truss rods work. String tension will add too much relief. I have worked on and built guitars for decades, and the goal, without strings, is a neck as flat as Florida (the most flat state in the union). When leveling the frets, a straight neck is correct; use a notched straight edge.
