i'm thinkin' about repurchasing a digitech bp-80 to set on whammy permenantly (since the actual bass whammy is out of production). i once owned it, but sold it because i couldn't figure it out, and thought it would useless on stage, and now i realize that it's justabout the only thing that has a whammy effect for bass on it at a good price. but before i decide to buy it i'd like to know: how do you set it on whammy, and does it give the effect i am looking for? i plan to use it to play tool songs, and i wanna use it in my band's music. thanks in advance guys.
