I have a Boss BCB-60 pedal board which goes left to right:

Boss TU-2 Chromatic Tuner, Boss GE-7 Graphic Equaliser, Boss BF-3 Flanger, Blackstar HT-Dual, Dunlop Classic Wah.

I'm thinking of replacing the Flanger with a Digitech Whammy Pedal, but am not sure whether it'd fit in? Would it fit length wise in there? Plus would I need a seperate power supply for it?
