Abstract
A pedal system and method for a musical instrument includes a supporting pedestal operatively connected to a foot pedal such that the foot pedal is pivotal to allow a user to control a musical tone in conformance with the angle of the foot pedal relative to the supporting pedestal. A rotating section is operatively connected to the foot pedal. A pressing member presses upon a contact surface of the rotating section. A leaf spring (or similar bias member) applies pressure on the pressing member causing it to press upon the contact surface of the rotating section. A pressing force adjusting structure to adjust the elastic force with which the leaf spring forces the pressing member upon the contact surface of the rotating section. The rotating section rotates about a central axis of rotation, and the rotating section rotates relative to the supporting pedestal. The rotating section has a contact surface parallel to the central axis of rotation.
