Hohner Pianet
The Hohner Pianet is a type of electro-mechanical piano built by the Hohner company of Trossingen, West Germany and designed by Ernst Zacharias. The Pianet was a variant of his earlier reed-based Hohner electric piano, the Cembalet, which, like the Pianet, was intended for home use. Hohner offered both keyboards in their range until 1968. The Pianet production consisted of two distinctly different mechanism groups with characteristically different sound. The first group, lasting from introduction to 1977, had ground stainless steel reeds, a pick-up using variable capacitance, and leather-faced activation pads. The second group from 1977 until the end of production used rolled spring-steel reeds, electro-magnetic pick-ups, and moulded silicone rubber activation pads.
The Hohner Pianet is an electro-mechanical instrument, and needs to be connected to an amplifier to produce an audible sound. It had 61 keys ranging from F1 to F6 (43.6 Hz – 1396.9 Hz). Later models had 60 keys, missing the top F. Each key is a single lever element pivoted on a fulcrum point with a spring to return it to the rest position. The key is extended at the rear so that a pad can be mounted over a tuned spring steel reed. This pad adheres to the reed when at rest, and lifts and releases the reed causing it to vibrate when the key is depressed. The vibration of the reed is converted to an electrical signal by a pick-up. The resulting sound has a complex mixture of harmonics when the reed is first struck, which later reduces to a cleaner sustained tone.
Early Pianets feature a knee lever volume control. The early 1960s Pianets (Pianet, Pianet C, Pianet CH, and Pianet N) featured lids which opened in an upright 'V' to form a music stand. This feature was introduced on Cembalets and became common to both instruments. The C and N models were equipped with a vibrato circuit operated by a switch mounted next to the keyboard. The N models used a variable-resistance volume pedal cabled to a socket on the rear of the keyboard.
The Pianet evolved from the earlier Cembalet, introduced in 1958. Both instruments were designed by Ernst Zacharias. Zacharias became interested in keyboard instruments such as the clavichord, harpsichord and organ as a teenager, and studied electrical engineering at the University of Kiel. He began working for Hohner in 1954 after meeting designer Siegfried Mager.
The Pianet evolved through a number of model changes. These included both self-amplified versions and versions that required the use of an external amplifier and speaker. The most popular model, the Pianet N (denoting "natural wood finish"), evolved through two different specifications. The N had side-mounted ‘inverted-V’ legs, and could be equipped with an optional 12-watt valve amplifier, the Amplifier CP, which mounted below the unit in front of the player's knees.
The Pianet soon found popularity with music groups of the 1960s, including the Beatles, the Zombies and Manfred Mann. This led to Hohner to producing the Combo Pianet model in 1972. It was designed for the performing musician, without legs, and intended to be placed on top of another instrument.
In 1977, Hohner began producing the second group of models and ceased production of the Pianet N and Combo Pianet. The second group had two models, the Pianet T and M, and a hybrid version combined with a Clavinet, the Pianet/Clavinet Duo. These featured a change in design from electrostatic pick-ups and leather and foam pads to electromagnetic pick-ups (like the Rhodes piano) and silicone rubber pads. The reeds were also changed from the ground finish of the earlier type to a smooth milled finish, making them incompatible with earlier models.
The new range of Pianets had a mellower sound than earlier models. While it could not lend it itself well to rock music, it was aligned more with musical tastes of the time, such as the sound of a Rhodes through a chorus pedal. It was advertised as being practical and portable, but this was misleading as it did not have an inbuilt amplifier or speakers. The M model, designed for home use, was built with a wooden veneer console case with internal speakers, while the T model was vinyl covered and designed for live performance. Subsequently, Hohner produced the Pianet/Clavinet Duo model which combined a Hohner Clavinet (essentially an electric clavichord) with the Pianet T in one instrument, with an integrated preamp that allowed the player to combine the two sounds. Production ceased around 1983.
