Tapes affected by sticky-shed are those that were made by Ampex/Quantegy such as 406/407, 456/457, 499, and consumer/audiophile grade back coated tapes such as Grand Master and 20-20+, [citation needed] as well as those made by Scotch/3M including professional tapes such as 206/207, 226/227, 262 (though not all 262 is backcoated and therefore isn't affected), 808, and 986 as well as audiophile ...
