In its time, the Wurlitzer EP200 was the only serious alternative to the Rhodes electric piano and found fame with bands such as the Small Faces, Supertramp and many, many others. Generally, it tended to be more popular in the UK than elsewhere where the Rhodes was favoured (especially in 'jazzier' circles).
Like the Rhodes, the sound was created by a hammer hitting small flat 'reeds'. The vibration of these reeds was turned into an electrical signal using an electrostatic pickup going to a mono output. The sound is not dissimilar to a Rhodes but has a brighter quality to it (exaggerated in Supertramp's hit 'Dreamer').
The EP200's simple front panel offered just volume and a single control that governed a 'tremolo' effect (simple amplitude modulation).
