Have NEVER had this problem...including with my few bargain tapes...!

Reading this, I realize my "illusion" of "cassette permance" may
well be exactly that...!! At the age of 66+...and after two major
head injuries (both diagnosed as affecting my hearing)...and a
couple of decades (give or take) as "head man" in an electric
blues band...standing WAY too close to Fender Twins turned
up to 10 to get desired distortion levels...my hearing ALSO
suffers from "loss of highs!!"
BTW, C-120's always carried warnings of "short life," and
were NEVER considered for archival use...?!
