Welcome to Super Duper Tapeline, cassette tapes since 1985

Due to recent increases in the cost of tape we have restructured the C-Length prices more accurately to reflect the tape cost inside the cassette housing. If tape lengths are short then the price increase will be much less and the tape stock will last longer. Our standard ferric type 1 tape is now a higher sound quality grade than our previous standard ferric tape for all our ferric cassettes up to C105.
