So I recently bought this 5 kg all maple mojomachine from Japan, and the sound and looks are great. It was listed as a «70’s greco», but nothing more. By the sound, look and feel it’s definately old. I can’t seem to find any serial number on the visible parts of the bass, so without opening up - does anyone know anything about this bass, or relevant information about Greco basses in the 70’s? I added some photos, if they’re to any help. Much appriciated!
