RE: Your really old post about expression pedals. I have done a mod of an old Cry-Babt with t 10K pot and it works. But, I would love to beable to activate it with the toe switch. Can you show me how you wired the switch? The way I have it, in one position the wha is activate (I only use this pedal for wha) but in the heel position and moving the pedal has no effect. In the other switch position, the wha works as expected. But for now I am having to activate it via assigning a switch on the Helix to bypass for the wha. is there a way around this?

Cool, its been a while since I did that mod. It was all done with an RFDuino. I wired a SPST switch to one of the GPIO taps. I think the wha originally had a DPDT switch that I replaced. Your issue likely is with that. I have one lead going to the GPIO input and one to ground (I think). In any case, the wrong switch will cause you many headaches. Note that I am doing this all via a midi connection and have code running on a RFDuino. I am not using any 1/4 connection on the Helix. My mod is very different than a 10K pot. The pot and switch are connected to a CPU where I read the analog input from the pot and switch and send midi commands. I saw your last post on the thread and you may be doing something different. In any case, sounds like you drilled a second hole for the switch to connect to the Helix? If so, you need a different switch. Look that up, but hopefully the info above gives you some help. Cheers and good luck!
