Hi Jim
Looking at the videos again and asking for advice about effects to some people i know, this is the guess:
-the two little pedals (blue and brown) look like the TC Electronic pedals: a delay and an overdrive. http://www.tcelectronic.com/guitar/pedals/
-A Jim Dunlop Wah wah (the big one)
-the white pedal is the Boss tuner pedal that I guess he uses for the lap steel. Unless he plays a tunable accordion!!

This is a guess from looking and listening. I could be wrong! I'm human after all.

cheerio
