Well as always thanks for kicking this one around, it's back in working order, almost "just exactly perfect." My problems started when I was messing with the settings. Sometimes I like to set it up to get that Barton Hall 'Dancin in the Streets tone which it does beautifully but for what ever reason this time I couldn't get it back to normal. New Battery in the guitar, checked cables and even plugged direct into it, all fine. I found that picking directly over the selected pup starting with a light attack to very aggressively got the signal to track normally. It was almost as if the signal needed to get up over the "hill"of the wah sound. Once I got it to track normally it did it every time no matter how hard I picked ect. The odd thing is that Jerry seemed to have this problem in the "Closing of Winterland" DVD. When he first turns on the MuTron at the beginning of Fire he just shoots up the neck on one string two or three times, this is exactly what I did to fix the problem. I apologize I can't speak better teck to give you guys a clearer picture of what I was encountering.
