Yamaha's excellent MIDI converter for electric-acoustic guitar or bass can take signal from any 13pin pick-up adapter. It can also convert instrument's analogue signal into MIDI data via the 1/4-inch input. Your electric guitar can now play a huge selection of sounds normally found on a synthesizer. You can even mix synth voices with regular guitar sounds, or play two voices at once, one from each side of a "vertical" or "horizontal" split position and in real-time too! Note that the device does not have any sounds on its own, it must be connected via a MIDI interface to a hardware-software synth to "play". It goes with the Yamaha G1D pick-up adapter, 6 meter 13pin cable, original 12V power supply and user manuals. Used rarely and only in the studio it is in perfect functional and aesthetic condition.
