Attachment device for stringed instrument and coupling system for use with the same

Abstract

An attachment for use with a stringed musical instrument comprises a rotatable shaft and groups of one or more string engaging elements coupled to the rotatable shaft. Each string engaging element of a group is positionable in a first orientation for driven rotary engagement with a corresponding string of the musical instrument. Each string engagement element is further positionable in a second orientation. The attachment further includes key actuators operatively associated with the string engaging elements, and each key actuator is manipulable so as to urge each string engaging element of a group into at least one of the first orientation or the second orientation. In an embodiment, the string engaging element(s) operated by each key actuator are rotatable wheels that rotate at a slower rate or a faster rate, depending on whether or not corresponding strings is/are bent toward the corresponding wheel(s).
