Be sure to add me to your favorites list Rare Original Genuine Roland GK-1 Guitar Synthesizer Driver Part with it's 16' Foot Cable and 24-pin Compatible Attachment. No Pickup Included Here. This is for Use With Roland GR-300, GR-700, GR-100, and GM-70 Guitar Synths This is a hard to find genuine Roland part from the 1980's, a GK-1 Guitar Synthesizer Driver Unit (Just this Unit Only, No Divided Pickup included Here). This part is made up of the GK-1 synth driver, with it's attached 16' foot long cable with a 24-pin connector at the end of it. It is NOT compatible with 13 pin cables or synthesizers. It is used to control the older Roland 24-pin guitar synths like the GR-100, GR-300, GR-700 and GM-70 from the 1980's. This is just for the unit itself in good condition, as shown in the photos. You will need a Roland GK-1 compatible divided pickup attachment in order to use this with your guitar synth controller. It is black in color with the cable being closer to a dark gray color. No divided pickup, no other cables, no mounting hardware, screws, or manual are included here (and obviously no guitar or guitar synth included either). Genuine 80's vintage Roland part, made in Japan! Again, just to make sure it's understood, this is just for the parts shown in the photos ... the GK1 synthesizer driver unit, with it's attached cable with a 24 pin connector on it. See my photos!
