A string mount system and method of installing guitar strings in an acoustic guitar. The string mount system includes a tonebar having a rod including a length extending from a first terminating end to a second terminating end. The tonebar includes a constant diameter extending along the length of the rod and the constant diameter is less than an inner diameter ball end of each string in a set guitar strings. The rod is located in a hole in each of the ball ends. The tonebar, with the mounted strings, is pulled against a bridge plate of the guitar. The strings are tuned to pitch. The strings are acoustically coupled to the bridge plate and to the sound board to vibrate the soundboard to produce acoustically amplified string tones.
