FROM WIKIPEDIA......The Pianet is a type of built by the company of , , from the early 1960s to the early 1980s. The designer of the early Pianet models was , basing the mechanism closely on a 1920s design by []. The Pianet was a variant of the earlier reed-based Hohner electric piano the which, like the Pianet, was intended for home use. Hohner offered both keyboards in their range until the early 1970s. 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.........THIS UNIT is used and has 3-4 bad notes, and could probably use some fine tuning, however we are selling it as a project, with no warranties, and no crybabies after the sale...HOWEVER...this is one cool keyboard, low out put yes...but you can hook up pedals and processors in line and this would be excellent for a punk rock band...or an easy listening band with the mellow, beautiful tone....this is a piece of rock and roll history...but this looks light but weighs around 65 pounds, so dont ask for any deals on shipping, thanx from Fortmadisonguitars...there's only 1way 2rock...and low ballers....please dont make any stupid offers, Im not desperate...
