Many serial numbers on guitars built there during this era use the first digit to indicate the year the guitar was produced, so the leading "0" in your guitar's serial number could indicate 1990, but this is all speculation. (This same guitar also appears in Westone's New Horizons catalog from 1989.) Specs include an unspecified body ...The headphones arrived in a plain box with Westone packing tape. Inside bubble wrapped was the Westone monitor vault. On the front etched were the words handcrafted for my name, serial number and the date of production. Inside were the monitors with cable, oto-ease and a cleaning tool.
My second guitar ever was a Vantage VP795. Bought new around 1980. Great guitar to develop on as a young player, especially having struggled with a Daphne Blue '65 Mustang beforehand. Plugged into a Lab Series L5. It was such a good guitar given its affordable price.
