Alright, there's a song, where the guitarists starts to solo for the second time, and it sounds odd. ( A good kind)
It sounds as if he's pushing down on a whammy bar whilst playing?
Listen from 3:13 to 3:16 to get the sound I'm asking about.
Does anyone know what he's doing to achieve that certain sound? Has me confuzzled.
Thanks in advance!

Yea it sounds like it. Joe Satriani and maybe Steve Vai, use this technique. It can produce some interesting results but takes a little practice to get right
