This is one of the pedals that John used very briefly during the Stadium Arcadium tour, for an unknown reason/purpose. The pedal is kind of weird piece of equipment, as it’s sort of a volume pedal and a wah 2 in 1 deal. On top of that, it also has a built-in fuzz and an octave effect.
As always, if you happen to come across a video of John actually using it in a live setting, be sure to leave a comment below.
John used this wah on his solo album “the Empyrean” you can hear it on the song “Ah Yom”
