Flake - Jack Johnson

Hi Guys,
I know this isnt really a question about chords and stuff but i was wondering if anyone knew what pedal he uses in the song when he does his solo at the end if any?
Here is a vid of the song, the solo is about 3:15 into the song. I know this isnt the proper vid but its the only one with the solo in it.

Any help would be wiked.

Thanks

The solo was played by Ben Harper, probably on a Weissenborn guitar with a slide. Doesn't sound like a pedal to me.
