The Roland GI-20 is not technically a guitar synthesizer, but rather a guitar-to-MIDI converter with no tone generation capabilities of its own. It is the successor to the GI-10 and uses a 13-pin cable to interface with a guitar pickup, such as the GK-3A, GK-3B, GK-2A, or GK-2B.
It has a transpose function and can shift notes anywhere from +2 to -3 octaves.
