It can be attached to the guitar with the included adhesive tape, and used by connecting the device's phone jack to the guitar's output and then to a guitar amplifier, etc. There are two types of switches: a push-button switch and a toggle switch, allowing for different playing styles. The sound produced is the same as that of other kill switch devices, such as TYPE.A. Included: Adhesive tape, one-year warranty.
