Yeah man I have no idea what was with Zakk's tone... had WAY too much chorus. See his new guitar? Looks like shit... Splittail shape + typical Gibson headstock = no go... plus the bullseye with the black edges just made it look tacky as hell, lol.
Here's a pic I took from the vid, from those who haven't seen it and want to:
Lol @ Zakk's head in that pic.
EDIT: Here's a better one.
Another thing I found weird as hell was the solo... he never touched the wah pedal but you could clearly hear it in the tone... and he never turned it off after the solo, but the rhythm tone sounded normal, not like the wah was toe down. Meanwhile the pedalboard was clearly sitting there. Maybe the one on the stage was just for show and someone in the back was controlling his wah? But what would be the point of that, he's never done it before? Weird shit... his foot stayed on the speaker the whole solo.
