Abstract: A reduced-friction pad is positioned between a tremolo and a guitar body. The pad substantially prevents direct contact between the tremolo and the guitar body, and reduces friction produced when the tremolo is pivoted or moved. The result is a tremolo which more reliably returns to its original position. The guitar also includes a roller block for accommodating a guitar string. The block includes a chamber which houses at least one low-friction shim, and a low-friction roller, the shim and roller being held within the chamber by a snap spring. The roller block can be implemented at either or both ends of the guitar, and can also be installed on a tremolo. The roller block reduces friction on the string, and enables the guitar to be more reliably tuned.
