TAPE MACHINE HEADS
Playback and record heads have always fascinated me.
They sit there all shiny and solid but when you insert a cassette and press play
they make you sing and dance! Standard tape machines have one head that records and then it also plays back the tape. You cannot hear what you have on tape until you play it back. Three head machines on the other hand allow you to monitor what you record as the record/playback heads are in one block. These were always more expensive machines and usually sounded far better but there are some two head machines that come really close.
Let your ears decide.
