Like roundwound strings. Who needs those? Flatwound strings, now that's the sound of a bass! Or who needs pneumatic tyres when solid rubber tyres work?
BBOT bridges sound fine. They were cutting edge technology when they were introduced. Then amps and cabs started to evolve and the possibility of making something better arose. Upgrading a bridge doesn't imply the previous version sounded bad, but we are an inventive lot, so if we can make things "better" we will, and sometimes "better" really does sound better.
ps spelling, again!!!
