ABSTRACT:
A string replacement assistance apparatus is used when the strings of a stringed instrument equipped with a tremolo unit are replaced. The tremolo unit makes a pivotal movement in arm-up and arm-down directions by an operation of a tremolo arm connected thereto. The string replacement assistance apparatus includes a base section which is to be put on the body of the stringed instrument and a holding section which is elongated from the base section and holds the tremolo arm to prevent the tremolo unit from the pivotal movement.
