Knowing some of the parameters that Jerry used for his wah sound in songs like "Estimated" and "Stranger", I tried duplicating it on my RP (digitech). Jerry used a Mutron, played with overdrive, and an envelope filter through a boutique amp miked up to play though a Jbl. Or something like that! Has anyone tried this? The Wah preset on the unit has a lot of parameters like cabinet, gate, etc. things I'm not sure about. Any ideas? For example, what would the pick up setting be? Or the envelope filter, anyone have an idea of those settings? Anyone have any ideas, I'm getting a little frustrated..a bag of pecan sandies for any help!
