I have 2 Yamahas BB :
The brown one with the maple head is a 400s from 1983 and the cherryburst with matching head a 414 from 2013...
I like them both but do prefer the 400...
It somehow looks more quality build (wich it actually is)
i've got a sneeky suspicion that my wife's boobs are counterfeit.... but they feel great and it sounds nice when i play them well...so i don't mind..;)
