[quote name='fatback' post='1096182' date='Jan 20 2011, 11:29 AM']My bb400 serial is on the headstock, but it's small and just stamped in, so it's very hard to see unless you angle the light.
Yamaha (U.S.) tracked the serial down for me with a phone call. Service or what.[/quote]
Thanks - I found it on the back of the headstock, very faint in tiny letters!
