MXR Standard Series instrument cables are your choice when you want a cable designed for musicians, by musicians. MXR instrument and patch cables are built with high-quality oxygen-free copper (OFC) conductors that won't tarnish and interfere with signal flow, and their OFC spiral shielding helps block RF interference. The Standard Series instrument cables also have durable, flexible PVC outer jackets and rugged TS connectors that are built to last.
