here is the gear list from the picture. at one point or another, i've played with the following so I know what they are from the picture. I thought Gabby was using a Boss DS-1 at first but the DS-1 has 3 knobs, not four.
john: (blue and white pedal) Boss DD-5 or DD-3, (black pedal) Boss Metal Zone or Hyper Metal, (teal pedal) Boss tremolo
gabby: Korg AX 10G, (orange pedal) Boss Turbo Distortion
