A brand-new 13 pin DIN female socket connector for chassis mounting. Compatible with Atari ST computer systems, Kenwood amplifiers and in-car entertainment and CB radios. This is a quality product - please do not confuse this item with poorly-made standard 13 pin connectors made from inferior materials.
Only reason for lower rating is that these ones do not have the locking key cutout for the Roland GK-2 / 3 cables. This wasn't obvious in the description.
Still, good product, just have to "modify" them using a dremel to work with the Roland cables.
