i need a good description/sound clip of this in action. im after this effect that i heard on some black label society songs, and zakk only uses 4 pedals so i think its gotta be the rotovibe. what im lookin for it kinda sounds like when you bend the string too far and it kinda goes in and out when it goes outta the pickup's magnet field for that string. so i think its the rotovibe, but can anybody confirm this?
