You're using the neck pickup on your guitar yes?
It just seems to be a little bit of reverb.
Signatures are overrated.
you can download effects from a site for POD's you should look for them (i'd give you the link but i dont know it)

Quite alot of gain. Sounds like he's got a fair amount of reverb too and probably got the treble knocked back a little bit. I'm not at home so I can't mess around with my amp to check, but that should get you close. Use the neck pickup too.
