Planet Waves Circuit Breaker cables feature an integrated mute switch that prevents loud pops or squeals when unplugging your instrument. Simply press and hold the button to activate the mute function and unplug. When you re plugged in and ready to go release the button to reactivate sound. The right angle plug is a great choice for plugging into guitar side-mount jacks and effects pedals. The 10-ft. length is ideal for shorter runs such as guitar-to-pedal board and smaller stages. The 20-ft. length is ideal for longer runs such as guitar-to-amp and larger stages.
