The Roland GK-3 Divided Pickup allows you to turn any steel string electric guitar into a synthesizer controller quickly and easily without any modification or damage to the guitar. Use the GK-3 to send accurate performance data to guitar synthesizers such as Rolands GR-55 and the Boss SY-1000. The GK-3 is for sending individual signals from each guitar string to GK compatible devices. It is carefully designed for guitar performance by having a large GK knob and a Select Switch to change from synth to normal guitar tone or both of them blended.
