Many musicians claim that the iconic sound of the Wurlitzer® 140B is absolutely the most vibrant, the most enveloping electric piano sound that has ever dominated radio waves. The "Wurli" was made between 1954 and the 1980s and used a metal core, small blades that hit the hammers by a true piano action. In an attempt to improve them, Wurlitzer went through four different rods again. The 140B, produced in 1962, was the first solid-state model. Under rebuilt.
