Same here. What I did find it useful for was boosting the treble on poor fidelity recordings by rerecording with "B" but then leaving it off during playback. Then came Dolby "C" . . .

Indeed Freddo30. During the 1980s I was recording both vinyl and CDs to cassette using a Harmon/Kardon cassette deck. Using CR02 (Chrome) tapes I would challenge anyone to detect the sound difference between the cassette and CD (or vinyl) during tape playback using Dolby B.

Thanks for the explanation Bob ; I rarely used it because of the treble reduction. And you needed it both on -record- and -playback- if I recall correctly.

The treble reduction occurred only on heavily marketed inferior quality tape decks. Dolby B worked very well on quality decks in reducing tape hiss without altering the original audio quality. However, pre-recorded so called Dolby B cassette tapes never tracked properly due to high speed mass copying and caused significant treble loss during playback.

To these ears it simply lowered the treble, so of course the hiss was reduced.
