I picked up a used Ibanez that I'd like to do some research on. It's my first Ibanez so I don't know that much about the history yet. Is it possible to determine the year it was made from the serial #? It's a custom made instrument so it has no model printed on it. It was made in Hollywood, CA and seems like an S series with a humbucker and 2 singles. Anybody got any ideas on how I can find out more about this new axe as the lady I bought it from was clueless?
