Welcome to the Milwaukee Servoelectric Guitar Project The Milwaukee Servoelectric Guitar Project is a volunteer effort to promote the advancement of servoelectric guitars and their design. Learn how to build this versatile instrument and advance the boundaries of experimental music. What Is a Servo Electric Guitar? A servoelectric guitar is a fretless guitar that is played by controlling servomotors that change the tension of the strings over an octave or more on a real-time basis. Tuning is maintained by closed loop tension feedback for rapid and predictable response. Relatively small electrical motors and DC servo amplifiers are possible through a novel compensator spring design. How Hard Is It To Build A Servo Electric Guitar? Using the Milwaukee servoelectric guitar design, a servoelectric guitar can be constructed with a relatively modest home workshop having a jigsaw and electric drill and using standard components available from a hardware store, electronic supply catalog, hobbyist websites, and surplus parts dealers. The project is not simple, however. You should have access to basic electronic equipment including a voltmeter and oscilloscope and a good working knowledge of electrical circuitry or friend who has such knowledge. The current prototype was constructed using the additional tools of the table saw, drill press, and power sander.
