D Addario Circuit Breaker cables feature an integrated mute switch that prevents loud pops or squeals when unplugging your instrument. Simply press the button to activate the mute function and unplug. When you re plugged in and ready to go press the switch again to reactivate sound. The right angle plug is a great choice for plugging into guitar side-mount jacks and effects pedals. The 20-foot length is ideal for longer runs such as guitar-to-amp and larger stages.
