Nickel plated, straight plug ( long type)
The long type plug cap is designed to be easy to insert and remove from the Stratocaster's boat jack. The plug shaft is φ6.3mm, which fits perfectly into the inch-sized jacks used on most guitars. This has the advantage that it is difficult to disconnect even if it is a small thing, and there are more contact points between the plug and jack, which has a positive effect on the sound quality.
