I've had this cable for five years. Works just as good as the day I bought it. For gigs, practicing, and rehearsing the ability to completely mute my base/guitar is indispensable. If you want to leave the amp on while changing instruments, you can use it to prevent the "pop" when you change on a normal 1/4" cable. Other times, I just want to go acoustic for tuning or working out a fingering without interrupting another player. If you need to put your instrument down, you don't need to touch the amp to kill the feedback/hum. My only regret was buying the 90 degree end. It does not go into my telecaster's recessed jack. Perfect for my bass, though. Sometimes I will put one between the pedal board and my amp, allowing me to move pedals around without needing to turn off the amp.  And because of the design, you can shorten it/cut out a damaged section and just reattach the end pieces where you need them. With how well this thing has aged, I don't think I'll ever need to buy another.
