Jimmy never used a Whammy pedal in Zep days.... NFBM is a phaser, as is Achillies and some Kashmir live parts .... Listen to Black dog from 'NoQuarter' dvd extras..... Thats a whammy pedal... Awful thing....
I think the reason JP doesnt play live anymore is obvious...... Obvious from the performance at the reunion gig.... obvious from the latest vid of him playing kashmir on acoustic.....
On the dvd, How many more times,Albert hall, when the band quieten down,and plant is making hissing noises... listen carefully... someone yells 'shut up' very loud and direct at plant.... there's always one.....
