The tuning system used on the Gibson Robot Guitar is based on the aftermarket Powertune system, which was developed by the Tronical Company of Germany. The Gibson system uses the standard  style bridge typical on their guitars, but modifications were made to have individual  saddles that transmit each string's pitch to the . The computer analyzes the signal, and then controls each of the Powerhead Locking Tuners. Each tuner is run by a small  motor that works in sync with the bridge to bring the string up to pitch by altering the string's tension until it is within a desired tolerance. The entire system is powered by a lithium-ion  housed in the control cavity of the guitar.The Robot Guitar has the standard four knobs for individual pickup volume and tone controls; however, in place of the bridge pickup tone knob, there is the Master Control Knob (MCK). The control functions like a “push-pull” knob: when in the down position, it functions like a standard control. When in the up position, however, the MCK is what coordinates the automatic tuning for the guitar by sending the information and power to the neck PCB through the strings. Then the PCB activates the robot tuners by contact.Users can choose from seven factory presets for tunings, six of which are editable. Each tuning can be returned to "standard" tuning of A (440 Hz) by simply pulling up on the MCK knob, and strumming the strings lightly.
