Step by step tutorial video on adjusting the neck of your guitar. First you need to remove the truss rod cover to gain access to the truss rod. Make sure you have the correct Allen key when adjusting your truss rod. If your guitar came with it's own Allen key make sure you use that one. Put a capo on the first fret. To increase the tension on the truss rod turn the Allen key to the right. To decrease the tension turn it to the left. Always check the gap between the frets and the strings.
