The Pianet was a series of
electric pianos built by the
Hohner company of Trossingen,
West Germany from the
1950s to the
1970s. The designer of the early Pianet models was Ernst Zacharias, basing the mechanism closely on a 1920s design by
Lloyd Loar.Sound is generated by an array of metal reeds which are plucked by
foam pads, which have been impregnated with
adhesive (actually a proprietary viscous
silicone oil). The pads are connected to metal rods connected to the keys. On pressing a key, the pad is released, creating a tension which makes the reed vibrate. Electrostatic pickups mounted directly below the reeds transmit the sound to an
amplifier.
