Seth Worley's Pedalboard Setup

Played with my Custom Nash Tele with Lindy Fralins, through a Fender Blues Junior with NOS Mullard tubes and a Greenback.

What's that switch you stepped on at 0:15 to create that pitch-up effect? Is that an expression pedal for a Super Shifter, or is that connected to the POG2 somehow? Thanks!
