  1. This this channel and the Dr Z channel are my favorite on youtube! I never fail to learn something really valuable and I just adjusted the trust rods on all five of my guitars and they play wonderfully! Thank you very much sir!

  2. Thank you for this great video! I have a 7-string guitar which had its neck in severe backbow (fret buzz on first and second frets) which I was able to fix with the aid of these tips.

  3. THANK YOU. My guitar had been fretting and I didn´t wanna go to a place to pay some random dude 30 bucks just so he could do a crappy job. Literally took me 10 minutes to set up my guitar and the tranquility of being able to do this at home is incredible

  4. I'm adjusting the truss now I'm not afraid of it just don't want to mess up the neck. Thank you for the information and God bless you for your help and support.

  5. killer; awesome; thank you! I bought a Recording King about five years ago and never luthier it. I started with the first fret action, then I straightened the neck because I like it with no bow what so ever. Now it sounds awesome and I can't wait to record some songs with it. Sir, your voice is like a great song, after the video ended, I can still hear your voice! Hehe… That's how you know a great song, Serious!

  6. Never understood why guys like Gibson refuse to use a double action rod when it's clearly superior in design (I.E. never needing to be removed and set back to "zero" due to reaching the end of the thread)

  7. Hello friend. Please tell me, I want to replace frets instead
    of nickel silver to put jescar evo gold. Guitar acoustics Taylor, I'm afraid
    to aggravate the sound, they say a lot of high overtones will appear on the Internet, and there
    are plenty of them on my guitar. I want bronze ones because they don't
    wear out, but I'm worried that the sound will spoil. Is it possible to put jescar evo gold on Taylor? They don't put them in their factory, so I doubt it.

  8. My bullet tip comes loose when I try to get more neck relief! When I tighten it it catches and seems to work fine but my one piece maple neck is perfectly straight with 11s I can only get .20 neck relief at the 8th fret! When I have a capo on the 1st fret and finger where the neck meets the body! Can I JB weld the bullet tip to the truss Rod so I can loosen it? And get more neck relief.

  9. There’s a lot more to learn here, apart from the string’s action and rod adjustment.
    Some of them are: genuineness, benevolence, teaching and communication skills, simplifying and briefing the subject, and many more!
    Sir,…thanks a lot for your gracious, well prepared and absolutely professional video!
    Salute

  10. I have done a lot of reading about adjusting guitar necks and still couldn't get it down. Thank you for this video I Now understand it totally. This was a Godsend. Thank you lots.

  11. Thank you Dan. I have to say, I was always under the impression the there should be a slight up bow, how wrong was I – I’ve just followed your instructions to straighten the neck and all of a sudden, my guitar is playing like a dream. I can’t thank you enough!

  12. Many thanks! I bought a darling little Ibanez short-scale bass. It didn't start having some razzle until three or four days after it arrived. Truth be told I was pretty nervous about attempting a truss rod adjustment on my own. But with the help and encouragement of your video I got the job done. I actually spent about 12 hours feeling depressed when the problem made itself known; buyer's remorse set in like a plague. This was an online purchase and I dreaded the process of returning the instrument via FedEx more than I feared destroying my new bass with the Allen wrench. (Most of the razzle came from fretting the D and G strings at the first two frets. A quarter turn at a time, retuning after each adjustment and it plays perfectly now.) Thank you again!

  13. What about the tune-o-matic bridge?
    Do we have to adjust height of it as well after we adjust truss rod?
    And if so, which way should it be or which way is preferred or better?
    Should we set tune-o-matic first or truss rod first?

  14. What kind of truss rod does a 15 year old g240 have? single or double action? When I try to turn clockwise, it won't turn. Do I need to loosen the strings or is it maxed out. I think the strings are a little high and I have to press harder to form the chord to where I won't have dead strings.

  15. The interesting thing about the two-way truss-rod is that we can now make a guitar or bass neck that has a natural back bow to fight against the string tension. If you use the truss-rod to pull the neck straight before stringing up, you can then back off the truss rod as you tighten the strings to pitch. The advantage of this is that you are no longer trying to find a balance between string tension and truss-rod tension. The neck itself counteracts the strings, and stability is much enhanced.
