Changing the action rod inside an acoustic guitar is a relatively simple process that can be completed in a few minutes. The action rod is a metal rod that runs through the neck of the guitar and helps to adjust the string height. By adjusting the action rod, you can make the guitar easier or more difficult to play.
There are a few reasons why you might want to change the action rod inside your acoustic guitar. For example, if the strings are too high, it can make it difficult to fret the notes. Conversely, if the strings are too low, they may buzz against the frets. By adjusting the action rod, you can find the perfect string height for your playing style.
