August Forster currently produce six models of upright piano from 4 feet, 6 inches (116cm) high to 4feet, 9 inches (125cm) high, and five models of grand piano ranging from 5 feet, 7 inches (170cm) to 9 feet (275cm) long.
Essentially a conventional grand piano, the Elektrochord used two strings per note, except for the bottom eight notes. Only one string struck by the hammer; the other string, which is shorter and set at a much lower tension, is allowed to vibrate in sympathy. Electrostatic pickups placed on different parts of this string can be set both vertically and horizontally to achieve a wide range of tones and attack characteristics. As an optional extra the Elektrochord could be fitted with a radio or gramophone.
