Whats the effect?

Hi, i've been trying to replicate the rythym guitar on amy winehouse covering valerie by the zutons (the slower version) so i can back a singer.  I think its got some phase or flange and some reverb but i'm new to using effects and can't seem to pin it down.  Just bought a POD effects unit and i'm sure the sounds in there somewhere.  Thanks.  Stu
