amen...sometimes ole skool is good skool! LOTS of amazing iconic records made with an ambassador (and often NO front head!)A coated ambassador head was industry standard on bass drums for decades.
The modern taste in bass drums has changed however, being more punchy, louder in the mix and with extended lower end - hence the development of heads like Emad.
So it depends what you are after. If you are gigging locally, playing a wide variety of music, an Ambassador head should be fine.
