Guitar - Fixing Fret Buzz - Truss Rod Nut Adjustment
How to do-it-yourself instructional on making a truss-rod nut adjustment on a one year old Gibson Songwriter acoustic guitar (similar to a Gibson J-50) to eliminate fret-buzz. [Guitar buzzes] Now that's what's known as fret buzz. If your guitar sounds like that -- don't worry, it's not time to get a new guitar. It's just time to do a simple adjustment. [Music] [No dialogue] OK so you've got this lock-nut on this truss rod underneath the cover there and we're just going to fit it with this five sixteenths deep socket and we're going to just give it a little bit of a turn. So it's a new guitar and so I assume that the wood is swelling and it's become too tense against the truss rod so I back off the tension. The standard change of tension is a quarter turn at a time, meaning ninety degrees at a time. OK we're just going to slip on the deep five sixteenths socket, just like that you see. We're going to back the truss rod nut off, just a quarter turn to begin with, of course, that's what everybody does. OK so I like to slack it off a hundred and twenty degrees and then turn it up another thirty degrees to make it a ninety degree turn in total. Now having just done that adjustment, I'm just going to set it down and let the wood "take" and reshape a little bit before I go restringing it. You can see for yourself what the fretboard looks like after the adjustment. [No dialogue] For a ninety degree total reduction in tension but as with tuning a guitar string you like to come up to the tension on it rather than just go down to it. So, if you're a guitar player I'm sure you understand what I'm talking about: you don't tune down, you only tune up. So that's what I did with the nut was I backed off further than I had to and then came up to the tension that was required. [Strums] Sounds OK now.
