Bender for altering pitch of stringed instrument

A bender for altering the pitch of a musical instrument including a plurality of strings substantially independently adjustable by the bender, thereby enabling the strings to vibrate at a plurality of pitches;

• at least one pedal or lever;
• at least one linear potentiometer responsive to movement of a pedal or lever,
• the potentiometer being able to produce output voltage signals;
• a servo motor associated with one or more potentiometers;
• at least one cam capable of engaging one of the strings;
• a logic controller configured and programmed to control the relationship between the potentiometer voltage output and a servo motor(s) such that the servo motor moves a cam into and/or out of engagement with the associated string and thereby modifies the pitch of that string;
• by modifying the engagement of the cam and the string based on the position of the servo motor.
