Semi-professional absolutely revolutionary model tape recorder from Philips: type EL 3542 D. This Philips tape recorder can be considered as one of the first 4 tracks recorders in the world!! The EL3542 also has a "trick key"; a catch on the front of the recorder which held off the tape off of the MOP. So one could take a second recording over an existing recording which consequently led to funny effects. such as duo play (sound with sound) and multi play (sound on sound). One person could form a duo with itself or a combo. Also this recorder has the possibility to play stereo tapes.
