WORKING CONDITION: Poor. The heads have been cleaned, but the noise floor is still extremely high. Only 5 keys produce a faint sound over all three of the selectable voices. The motor works and changes pitch via the pitch adjustment wheel. Please Note: This Mellotron is being sold AS IS.

PHYSICAL CONDITION: Good. The wooden casing shows signs of age but is stable and intact (see photos). All wooden keys are in good condition but need to be adjusted individually to achieve proper pressure against the playback heads. The front fascia panel requires some extra effort to remove and re-install. One of the four bolts that hold the feet to the bottom is missing, but unit remains stable and balanced. No missing parts or components otherwise and very good example worthy of getting a tune-up by a tech.
