- 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 thatís whatís known as fret buzz. If
your guitar sounds like that Ė donít worry, itís not time to get a new
guitar. Itís just time to do a simple adjustment.
- [No dialogue]
- OK so youíve got this lock-nut on this
truss rod underneath the cover there and weíre just going to fit it with
this five sixteenths deep socket and weíre going to just give it a little
bit of a turn.
- So itís a new guitar and so I assume that
the wood is swelling and itís 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 weíre just going to slip on the deep
five sixteenths socket, just like that you see. Weíre going to back the
truss rod nut off, just a quarter turn to begin with, of course, thatís
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, Iím
just going to set it down and let the wood ďtakeĒ 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 youíre a guitar
player Iím sure you understand what Iím talking about: you donít tune
down, you only tune up. So thatís 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.
- Sounds OK now.
