Something seems to have gone strange with the auto off settings on my wah pedal. I have them set to inactivity, 300ms, with a threshold of 10%. The way I would expect this to function would be that if the pedal was below 10% of the range and not moved, then the wah should switch off after 300ms. I'm pretty sure it used to operate in exactly this way. But no longer. It now cuts out after 300ms, regardless of the pedal position. A while back I noticed a bug when copying the wah settings from one block to another. It somehow set the pedal range max to 1000%. I had to go back in and manually reset them to 100%. May be related, maybe not. Question is, how do I fix the wah auto off?
