Adjusting the motion on an acoustic guitar entails altering the gap between the strings and the fretboard. Reducing the motion could make the guitar simpler to play, particularly for freshmen or these with smaller arms. It might additionally enhance the intonation and sound high quality of the guitar.
There are two foremost methods to decrease the motion on an acoustic guitar: adjusting the truss rod or sanding down the saddle. Adjusting the truss rod is the extra frequent technique, and it’s usually achieved with a particular instrument known as a truss rod wrench. If the truss rod is simply too tight, it could trigger the neck to bow ahead, which is able to increase the motion. Loosening the truss rod will permit the neck to chill out and decrease the motion.
