Using a guitar or bass equipped with an optional GK-2A or GK-2B Divided Pickup, the GI-20 can be used to trigger virtually any MIDI-compatible synthesizer or sampler, as well as out-putting your "natural" guitar sound for amplification.

Thanks to its convenient USB MIDI port, the GI-20 lets you quickly connect your GK-equipped guitar or bass to a variety of computer-based recording systems.
