What effect does he uses?

hi guys,

here's a song called Dancing Generation by Matt Redman .. and what would be your best guess for the effect he uses in the intro and verse part?

seems like something sort of overdrive .. but can't figure out any yet .. help here

sounds like a smooth fuzz blended with clean signal

could be a muff... don't really know though
