I needed a Play/Stop switch for my Zoom multi-effect for a bass player, and what better way to buy it when you can buy the Zoom brand directly than the Zoom FS01. It fulfills exactly this function 100% and its flat design is super convenient. A lot of kids advise that it's a waste of money for an ordinary switch. I've seen a few amateurishly made switches at home, and the switch for a lamp is a futuristic product compared to this one. Saving a few crowns in the stupidest place. But I don't condemn it, it's freedom... I can only recommend this switch to her!!!
