Attack – controls how long it takes for the effect to happen.
Pos – represents the current angle of that pedal, with 0% meaning the pedal is fully
heel down, and 100% meaning it’s fully toe down. If you don’t have a pedal connected,
you can still adjust Pos to get a “parked wah” sound.
Heel – sets how much effect you’ll hear when the pedal is at its minimum (heel down)
setting. Set it to 0% to have no effect in the heel down position.
Toe – sets how much effect you’ll hear when the pedal is at its maximum (toe down)
setting.
