Goodwill packed it poorly and FedEx tried to destroy it, but this Bontempi X451 still works somehow.
It's the last in the line of Minstrel/Master keyboards that Bontempi made and has sounds that none of the others have like Space, Guitar, Banjo and Brass. It also has a full octave on the left side (like the X401) making it longer than most of the other models which started with a bottom A for some reason instead of C.
