The WM-7 is arguably the most complex of all the Walkman models. It was the first to have electronic “logic” tape transport keys and the first to offer remote control. It is also the only model to have 3 motors, though only one of them is used for tape transport.
The introduction of the WM-7 brought several new features to the Walkman range. As well as the electronic controls, it featured auto-reverse, Dolby B noise reduction and a “hold” function that blocked all the keys when set.
