Oh shoot. I think I misread your original post, Archie. You’re talking about hearing the picks on the strings, aren’t you? My problem was my thumb pick hitting the head. Sorry about that.
If it’s your stainless picks making the noise, I wonder if smoothing them out with some fine grit wet sand paper might help. My old nickel picks are slick as a cow’s nose. Maybe yours just need to be smoothed out?
