A string bender mechanism for a string musical instrument having a bender assembly comprising a control member and at least two bender levers. The control member moving between a first position and at least a second position, being a rest and active position, respectively. The at least two bender levers have a first end and a second end. The first end of said bender lever is dimensioned or adjacent to the control member and the second end of the bender lever receives a string. When the control member is in the first position, the bender levers are at rest and a tone emanates from a plucked string. When the control member is in the second position, the bender levers move simultaneously, and a varied tone emanates from a plucked string. In an alternative embodiment, one or more bender levers may be replaced with a switcher assembly.
