Yes, been hearing it for years. I even have a drummer buddy who had the same pedal years ago and it had a similar squeak. It was considered a badge of honor! My group were all big Zep heads back in the day.
I'm Just Not Hearing It..., Do You???
I've been listening to Since I've Been Loving You but maybe it was lost in the transfer to CD because I remember hearing it in my youth (better ears?) on LP.
Do you hear it on your system and if so, does one media convey it better than another?
