The GR-1 uses a 13-pin connector and is compatible with the Roland GK-2A, Yamaha G1D, or other similar hexaphonic guitar synth pickups. Guitars with built in synthesizer pickups like the Brian Moore i8.13, Godin LGX-SA, and Roland-ready Stratocaster are also compatible.
The pitch tracking circuitry in the GR-1 is the same as those used in the GR-09, GR-50, GM-70, and GI-10 and note response will be at the same speed as in those units.
It uses an external 9-volt power supply.
