I'm making this video because very occasionally a neck on a guitar that I've set up for a customer with a very low action can flatten or straighten out slightly during transit. This is completely normal - wood undergoes these changes due to shifts in temperature and humidty - but in low, light playing actions this can lead to a re-introduction of buzz quite easily. A guitar with a higher playing action can tolerate small neck changes without any buzzing; one with a very low action at both ends and a flat neck profile will typically develop buzzing frets in the 1st half of the neck (if the neck flattens) or increasing playing action in the middle of the neck (if the neck curves more). On the rare occasions that a neck starts buzzing it's usually because the neck has flattened in transit due to temperature or humidity changes and as a result, the buzz is usually encountered in the first 3 or 4 frets from the nut.
This video explains this rare occurrence and shows my customers how to assess the neck to confirm that the neck has indeed very slightly changed its relief profile (flattened or curved more). It covers how to adjust the neck to regain the desired amount of neck relief.
Another important reason for making this video is to encourage customers and viewers of my YouTube videos to make it a priority to become comfortable making truss rod adjustments. You may only need to make tiny adjustments once a year - or even never - but the ability to set the minimum neck relief for the set up you have (and your playing style) will be a priceless skill. Too many guitar players have been led to believe that they are likely to damage their guitars unless they leave truss rod adjustment to the 'experts'. This is disempowering nonsense. This video encourages you experiment making adjustments ASAP - so you know exactly the difference adjusting your truss rod makes.
