This unit's in very nice shape and has been professionally refurbished. Includes original warranty card, sound setting sheet and cardboard box, though we suspect this might have just been the packaging used inside another original box since there are no markings on it.
We paid our tech for over 3 hours of his time to restore this unit. Here's what he did:
Replaced old battery snaps.
Cleaned all pots.
Cleaned keyboard key contacts.
Remounted battery holders.
Cleaning and full testing.
This unit works great, with one minor exception: although we disassembled it and cleaned it, the pitch bend pot occasionally glitches at the top of its range. If anyone's got a source for replacement pots, please email us.
