JT's Whammy

I've a question for John that I've been meaning to ask ... I noticed recently that he has a digitech whammy pedal in his rig. This is quite an unusual pedal for a bass player to use, being more often found in the arsenal of a guitarist. So, I was wondering which songs John uses it on. Thanks!

"Not often does I use it - the outro of "Notorious, " sometimes jamming away on "Girls On Film".. oh yeah.. second verse of "Come Undone" too. JT"
