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.

What Can I Do with a Milwaukee Servoelectric Guitar
