I saw Tool last night, and have some updates about his rig. 1. Justin does not have a Crowther Audio Prunes & Custard on his board... it's a Prescription Electronics Depth Charge 2. During "Lost Keys", a roadie brought out a secondary pedalboard out for Justin. On it was another Guyatone VT-X Tube Tremolo and three other pedals (possibly distortion). 3. I think Justin was using a Zvex Probe Wah during "Lost Keys". He would rock his foot back and forth during the song, changing notes. That's about it...
