Dual Contact Mono 2-Conductor 1/4" Jack. Open Circuit. Includes nut (3/8"-32 threading) and washer.
Tech's notes: "Dual contact mono jacks have become popular in recent years due to some aggressive marketing campaigns from certain companies. While they don't provide any greater conductivity or improve the clarity in your tone like the marketing hype might suggest, the extra contact does give you the benefit of a potentially tighter and more secure connection. Like all Switchcraft jacks, these are built to a high standard with reliability you can count on."
