I'm confused because if you look at a pedal board, it's usually right to left..plug into your first pedal on the right and signal flows left out to the amp. He can't wire his wah backwards lol.. therefore it has to sit at the end even though all these online diagrams place it first which is where most people would put it. But hold on.. I suppose "IF" his pedals were mounted upside down in that chip pan, that wah would in fact be first wouldn't it... ahhhhhhhh makes more sense. Filter - distortion - add to taste with EQ. Volume controls how much delay is added in spots. Those pedals flipped upside down confuse the shit out of everything common sense about signal path

(visually anyway)
