This is a detachable kill switch device for guitars. Attach it to your guitar with the included adhesive tape. Installation is complete by inserting the device's plug into the guitar's phone jack and connecting the device's phone jack to your amp or effects unit. There are two types: a push-button switch and a toggle switch, allowing for different playing styles. The toggle switch is ON-OFF-ON, and the lever moves horizontally. The caps for the toggle switch and push button are black by default, but can be changed to the colors shown in the images if desired. Please contact me with your color preference either initially or after payment. If there is no specific request, the standard black will be shipped. Included: Adhesive tape One-year warranty The product now includes the product name and logo, laser-engraved. (The first two images are the only ones updated, so they are not included in the older images.)
