To check this place a capo on the first fret and while pressing down on the string at the 15 th fret, check for approximately. Retune and recheck, tightening more if necessary.
Recheck and readjust as necessary. NOTE: If the neck is not responsive to truss adjustments, tune to pitch and let it sit overnight in a warm suitably humid environment to see if the neck will move over time. Back to the List. Was this answer helpful? Thanks for this. I agree; the neck angle is never mentioned,perhaps because it can be a problem to remedy.
Sighting down the neck toward the bridge can give you a pretty good indication of the amount of work needed. Awesome Instructable. Excellent detail! Another thing I have done with the cheap chinese instruments is to sand down the frets and sometimes file! As the price comes down the finish suffers, but the sound can be OK. Often the mother of pearl inlay is proud of the wood on the fretboard along with glue drips or crummy paint on the fretboard.
Keep up the good work! Thanks for the comment. Some classical guitars are constructed without a torsion rod. Such a guitar is usually hand crafted and aligned for classical fingerstyle playing. The typical inexpensive "classical" guitar should have the same adjustments I have outlined though.
On the other hand I have a very old acustic guitar wich doesn't have a torsion rod and the neck is slightly bent. I don't know if this has a solution. I'll try to figure it out.
Nice instructable. But why did you bother sanding down the bridge if the saddle is higher anyway? Good question. When you look at the saddle you see that the strings go over the saddle and then attach at the back of the bridge. The saddle seeds to rise above the bridge so that the strings angle down to their attachment point on the bridge. By angling downwards from the bridge, the strings apply enough force to press the saddle firmly onto the bridge.
The job of the saddle is to transmit the vibrations to the bridge, which distributes the vibrations over the guitar body. If I just sanded down the saddle without lowering the plane of the bridge then the strings would no longer anger downward to their attachment point; the saddle would not have enough force to keep it in place and start to buzz when it vibrates. Even after I sanded down the bridge I still found it necessary to cut a few grooves behind the saddle in order to further increase the angle of the strings.
Introduction: Acoustic Guitar Setup. By buildinganempire Follow. More by the author:. Unfortunately the neck angle is fixed when the neck is mounted to the body and cannot be adjusted unless it is detached and reseated.
Of the inexpensive guitars I have evaluated, this specification seems to be most variable. One solution may be to sneak a straight edge into the music store and inspect the guitar before purchasing. Since the thickness of the bridge can affect the sound of the guitar, I decided to cut a few string grooves behind the saddle to minimize the amount I lowered the entire surface.
Here is an answer I posted: When you look at the saddle you see that the strings go over the saddle and then attach at the back of the bridge. The saddle needs to rise above the bridge so that the strings angle down to their attachment point on the bridge. If I just sanded down the saddle without lowering the plane of the bridge then the strings would no longer anger downward to their attachment point; the saddle would not receive enough force [by the strings] to stay in place and start to buzz when it vibrates.
This assured that the strings would exert enough downward force on the saddle to keep it firmly in place. The other reason maybe more obvious is that if the neck is misaligned you could shave the saddle all the way down to the groove it sits in and still not have the action low enough.
In the case with the guitar pictured, I ended up sanding down the saddle to a point below the original plane of the bridge. If I didn't sand down the bridge the saddle wouldn't have even risen out of the groove! However, if your measurements showed that you still don't have the relief that you want, you still have room to make a second adjustment to get it closer to right. A tiny adjustment is all it takes. These adjustments can take some time to get right, so don't beat yourself up if you didn't get it right on the first try — especially if you've never adjusted a truss rod before.
Check your relief again after 24 hours. The neck of your guitar takes time to settle, so you might not get the full effect when you check it immediately after adjusting the truss rod. Leave it alone for a day, then check the relief again and make another adjustment if necessary.
Changes in temperature and humidity can impact the truss rod adjustment you've made. Include your email address to get a message when this question is answered.
Get your tools together before you start work. You can get basic tools online or at your local hardware store. You can also buy specialized luthier tools from a guitar shop, but you'll probably end up spending a little more money.
Helpful 0 Not Helpful 0. If you've recently traveled with your guitar, give it hours to acclimate to the space before you attempt to adjust the truss rod. Any problems brought on by varying temperature and humidity levels may correct themselves in this time. If you want to change the gauge of your strings, you will likely need to adjust the truss rod again so the neck relief suits those strings. Helpful 1 Not Helpful 0.
Submit a Tip All tip submissions are carefully reviewed before being published. If you don't feel confidant adjusting your truss rod or are worried about damaging your guitar, take it to an experienced luthier.
Helpful 2 Not Helpful 0. If your truss rod won't turn at all, take it to an experienced luthier rather than trying to force it. The neck of your guitar is slow to adjust, so the full effect of a truss rod adjustment may not be immediate. Don't turn your truss rod more than a quarter turn in any hour period.
Then, check your relief and adjust again as necessary. You Might Also Like How to. How to. More References 9. About This Article.
