Looking for a thin switch to sit in front of your HX Stomp to give you access to your FS4/FS5 functions? Look no further than our FrontAux! 2 switches aligned center of the existing HX Stomp switches, in a thin narrow-bodied switch, set at an angle for easy access/less accidental hits! The switch body depth is 0.91 in, with angled switches extending slightly beyond that. A TRS cable is needed to connect to your stomp; We can custom make the right length of cable for you, available here! https://pedalnetics.com/product/helauxy-trs-cable/
