Well maybe so but...you could have cleaned it off. The presence of verdigris begits more verdigris. A small brass brush, or stiff bristled nylon brush, along with a little alcohol does wonders for cleaning agraffes insitu. d.) that "stuff" "glogging" is not what causes the problem it is the stuff which extends out of and beyond the agraffe hole which dampens the string at the agraffe hole causing the muting tendency. My opinion. Jim Bryant (FL)
