sounds to me like Scott is playing his lap steel guitar.  he is definately the best i have ever heard at that particular instrument, his technique is amazing and it does indeed sound like a pedal steel guitar.  i dont know how he is doing that.  he has mastered use of the volume pedal but thats not what im talknig about, i mean the pitch or the slide/tone or something...it is def the player not the instrument.  his work on the Chamberlin album sounds the same.

i am scared to think how great it would sound if were actually a pedal steel guitar.  i would not be suprised if one of those monsters poped up onstage next to the B3 at some point
