okay i have been looking for this one type of sound it is used in songs such as

ocean breathes salty by modust mouse
here in your arms by hellogoodbye
honest mistake by the bravery

its a hard sound to describe but it omost sounds like the guitar amp is under water my favorite sound of the effect is the song by hellogoodbye
if anyone can tell me a pedal or way to make my soound sound like this i would really be happy
