This was the perfect solution for me. In using my Headrush Core I would often accidentally hit two footswitches at once which banks up or down the preset I'm own. This was a nightmare when it happened in a live setting and embarrassing and rehearsals. This little tour cap screwed onto the middle button prevents this from ever happening again. I played a show this past weekend with not a single problem. Great product. Glad I found it! One cool feature I found was that you can still access the foot switch with your finger. You just can't step on it. Again. Highly recommended product. Simple solution
