The Wurlitzer 200 A is a 64-note Electronic Piano with a keyboard range from A an octave above the lowest note of a standard 88-note piano to the C an octave below the top note of an 88-note piano. The 200A's were produced from the early 70's through the early 80's. The secret to the unmistakable sound of a Wurlitzer is that the strings found in conventional upright pianos have been replaced with struck steel reeds.
