I have searched, but "Whammy" turns up a whole mountain of threads... I'm thinking of buying a Whammy as a cheap way to see if there's likely to be any point in me getting a Pitch Factor. I'm not going to buy the Bass Whammy because the prices are silly, and from looking at eBay it seems the most common ones used are the Whammy IV and the XP-100 Whammy/Wah. Has anybody compared these two and formed an opinion that they'd like to share? Or has anyone tried one of them and found something unreasonably unpleasant about it that I ought to know about? I'm not interested in reproducing Justin Chancellor riffs, I wouldn't know a Tool song if I heard one, never listened to them, so any specific settings he uses aren't important to me. Please advise!
