Problem with HX Stomp and BOSS FS-7 footswitch in Helix Posted November 10, 2019 I had the same problem with a new FS-6 switch. I can't remember how I solved I just know the settings I used on the FS-6 at the end were completely 'wrong' when it worked. I think, I set it to latch instead of momentary. It's worth to ingnore the labels on the Boss and just try what works. The possibilities are not endless.
