Taylor Guitar Truss Rod Adjustment DIY Guitar Tip | Edwin-E

[@joeykahng6219]

Sweet! Haven’t adjusted my guitar in 20 something years. Haven’t played in 10 and now I want to play again, glad I found your video so I can properly adjust. 🤙🏼

[@Edwin-E]

Just be careful. Don't force it if too tight.

Edwin- Thank you SO MUCH for this. As I get older and my hands a bit arthritic, I was thinking of unloading my Taylor 12. This gave me the guts to adjust it myself and it's SO MUCH BETTER. Thanks again!

You're welcome. Enjoy playing!

[@cruzdearrastiamusic7749]

Thanks. I used a small 1/4 inch socket wrench (I couldn't wait to adjust the rod) and it worked perfectly. Thanks! It plays so much smoother.

[@Edwin-E]

Glad it helped! Thanks for watching and sharing your experience.

[@jonathanmcdonald5853]

Much appreciated! I found a good PDF file (printed card) I used to careful measure the mm down from 3 to 2, on my Taylor 224-k! worked awesome! Made a world of difference, may you be blessed for your kindness! No Luthier needed.

Thank you a lot for this video. This did the trick in adjusting my Taylor 214ce. Question: I have a Cordoba nylon stringed guitar. I’m wondering if this technique can be applied to nylon stringed guitars.

[@Edwin-E]

it is just the same, although, nylon stringed guitars has less tension compared to the steel ones.

[@Yeon8888]

Thank u man ! My 1999 USA Taylor 7 series sounds really great with super warm tone and great sustain. But I had been wondering why it’s action is so bad on the lower frets. It was really stress on my fingers trying to press the notes and chords. I finally know what need to be fix after watching ur video. Thank u!!! Now I can play without unnecessary straining. Beautiful grand warm sound.

[@Edwin-E]

Glad this video helped. Thank you too for watching.

[@wildizer]

Sounds like your nut slots are too high to me. check the gap between the strings and the top of the first fret. Should be 0.020" on low E & A, 0.018" on D & G and 0.016" on B & high E (all on open unfitted strings / without capo)

[@finalizedtrains]

Hello there. My Taylor is a model 110-GB. It's always had high action since new, so not pleasant to play (so I don't play it!). I just took it out, and am going to adjust the truss rod. The adjusting nut on this model is on the end of the neck inside of the sound hole. I'll guess the process is the same as the head stock end adjustment, but wanted to check out your video. Thank you. ...beautiful playing.

Thanks and be careful.

Sir Edwin , how about if the hex nut of the truss rod is damage , it's difficult to turn and it's slips when the wrench is inserted ,any suggestion, any remedy ?

[@Edwin-E]

Are you sure you are using 1/4" socket? Sometimes, others try 7mm and it can damage the nut.

[@bogdangrund3913]

Hello Edwin. Could you please answer my question. I have a Taylor 214ce plus and the problem is that I have buzz but only when a few strings a playing and the position of the chord is unusual. I have adjusted the truss rod, the action is high - 4mm. I don’t know what else could it be. And also I have buzz in other tunings which also doesn’t let me be fully open with my guitar. I don’t know what to do 😞

[@Edwin-E]

Make sure that frets are leveled.

[@colewastank]

So no need to remove any tension from the strings?

[@Edwin-E]

no. The strings must be in tune to set proper tension for correct adjustment. Thanks for watching.

[@calvinben6261]

Can i use the same 1/4 inch /6.35mm wrance on Taylor big baby?

I heard that Taylor uses 6.35mm just like the one in this video.

Hi Edwin is this method also work for the taylor nylon string? I'm thinking to do it on my 214ce N guitar.

[@Edwin-E]

Yes, although nylon strings have very little tension. In fact, most nylon stringed guitars do not have truss rod.

[@lesliebrennan3351]

Nice video. My Taylor 110E had multiple buzzing. Even took it to store i bought it and it still buzzed. Where do you get the measuring ruler tool?

[@Edwin-E]

I purchased the tool online. You can try amazon, etc. Maybe the frets are not leveled if you have multiple buzz.

[@nyacoustics8373]

I have an old aria acoustic guitar. When i remove the truss rod cover all I see is a regular nut that is at the bottom of the rod with some threads exposed. There is no eggcorn or bullet in front of it. There is no possible way to fit a socket in to tighten it since there is no clearance in front of the rod because the wood head stock is in front of it. It can probably be accessed with a open ended wrench. I need to straighten the neck. it has a bow in it and the strings are pretty high from the fret board. Any input?

[@Edwin-E]

I never seen a truss rod adjustment nut that is not accessible. It would be nice to see some photos.

[@aditmaharjan6084]

[@jeffroutledge9153]

Hey bro, what do I do If I want to lower the action on my 814ce but there is no bowing present? Can I still lower the action by tightening the truss rod and not have any buzzing or cause any reverse bowing? Thanks!

[@Edwin-E]

If the neck is already straight, then tightening the truss rod will cause reverse bowing which will cause fret buzz on the lower frets. If the action is too high, then probably needs a neck reset. Refer to my other video where I tried doing it. I recommend you contact an authorized Taylor service center if this needs to be done. kzbin.info/www/bejne/rHyZg2OwnLOcZsk

[@jeffroutledge9153]

He Edwin nice video. Do you know if the Taylor’s are typically bright and have a little string Buzz no matter what the adjustment is ?

[@Edwin-E]

Taylor has its distinct bright tone. I don't know about string buzz you mentioned. If it is setup properly then, it should be ok. And also depends on your playing style. If you strum so hard, then you need a bit higher string action.

Hello Edwin, thanks for the nice video. I have gotten a lot of help from you in regards with my Martin. I just traded it in to get a Taylor 114ce. Edwin, what a difference in the action, I have arthritis in my fingers as well as them being small. I really was struggling with the Martin. I have to change the strings though, they are 13s..I am going down to 11s, so I will have to adjust the neck a little. I like the sound of my Taylor better than the Martin, although the Martin had a little deeper sound, but play ability of the Taylor is the difference between night and day. Edwin, which do you like better. Thank you for your videos, they make things easier. DAVID

[@Edwin-E]

Congrats on your new guitar. And thanks for a very nice comment here. You are right about Taylor neck, it is really comfortable to play. I cannot decide between Martin and Taylor because I like them both. It really depends on my mood which one I would like to play and which guitar better suits with the song I am playing.

[@ryysen]

What if my 1st string height is fine (1.5), but my 6th string is pretty high (3). Any ideas po? I have a taylor 114ce

[@Edwin-E]

I think 3 possible causes. 1. The saddle height for 6th string is high. 2. Neck is a little twisted, 3. Bulge on the guitar body.

Hi Edwin, I’m not sure if you make Taylor Guitar action lower, turn Truss tod clockwise or counterclockwise?

normally, tightening by clockwise to counteract string tension. This will make neck straight if it is bowed inward, thereby lowering the action.

The purpose of Truss Rod Adjustment is to keep the strings as low as possible without buzzing when played relatively hard. I am saying relatively because it depend to the play style of each guitar player.
