CU-416 cable (forSL-4 series) CU-416 cable has excellent sound quality, flexibility, durability, and processability, making it not only for audio signals but also for DC cables. At 4mm in diameter, this cable has a very high potential, especially useful in pedal boards and rack systems. The CU-416 cable features natural sound and can be used for almighty connections such as effectors and switchers. The cable is the thinnest and flexible, so it is recommended for those who want to keep pedal boards compact. Unlike common plug construction, the core of the cable and the tip of the plug are joined inside the plug, so the joints are tightly protected and eliminate the cause of disconnection. The plug tip and the core of the cable are joined together at a dramatically short distance, thus preventing sound quality degradation and ensuring high sound quality. No soldering is used, so it is not affected by sound quality caused by soldering. Super space-saving design allows flexibility in narrow pedal boards. The worlds simplest structure and easy to build solderless plug.
