Might be a stupid question but why is my Wah pedal not working! in Helix Posted August 10, 2019 9 hours ago, rd2rk said: I just tested this because I couldn't remember for sure. WAH is assigned by default to EXP1 with Toe Switch enabled. VOLUME is assigned by default to EXP2 with Toe Switch enabled If ONLY the VOLUME Block is assigned, then the Toe Switch toggles the VOLUME Block ON/OFF. When toggled OFF, volume defaults to 100%. If VOLUME AND WAH are assigned, the Toe Switch toggles between WAH and VOLUME active states, but the VOLUME defaults to 100% when the WAH is active. Yes, confusing, which is why I always forget if I haven'y been creating presets in a while. To make it more confusing, it's possible to wind up with the Toe Switch functional, but the Expression pedal inactive. In which case, clear both blocks and start over! That's correct. I remember that the TOE Switch had to be pressed very hard the first time when my Helix was new. So I guess he has not noticed the Toe switch yet.
