DADDARIO / PW-AGRAP-2 Latching Circuit Breaker Plug This is a switch plug that allows you to mute at your fingertips. Unlike the common type that turns ON when plugged in, it's easy to use because it doesn't produce a popping noise even with an active bass. Also, the red push button makes the On/Off status visually clear. MUTE: Red part is visible ON: Push it in, and the red disappears, turning black! Convenient for switching instruments, etc. Functionality confirmed. Instant purchase OK. ===================== 1/4" plug, perfect for patch cables and instrument cables.
