Abstract
Abstract The invention is a microtuner, for stringed musical instruments with a headstock and individual strings, that includes a roller cam assembly which receives an individual string, and a tuner assembly, which receives the individual string from the roller cam assembly and adjustably presses down onto the individual string. There is also a lever lock string system assembly that pinches down onto the individual string and releasably locks it into position. A clamp or screw assembly secures the microtuner to the headstock. The cam of the microtuner can also be made of a variety of materials to produce an overall sharper sound or an overall softer sound.
