No car collector is going to salivate over a 2009 Honda Civic when it's sitting next to a 1963 Corvette. Sure, the Honda will technically out-perform the Chevy in almost every area....but so what?
Same thing is going to be true, to a collector, for vintage drums.
People often ask, "Why aren't there any good movies being made anymore?" Well, the answer isn't that there are no more good actors, writers, etc. The answer is that the movie-making process has completely changed. Movies are sold on an international basis now. Language barriers keep the movies sequestered to a much more limited market....unless you can make (and sell) movies that don't rely on language! Just make a plot that has a lot of chase scenes and explosions -because everyone can "get" that no matter what language they speak or what culture they are from....thus, more money can be raked in. There is no demand for "good stories" on an international basis.
Manufacturing started to see that it wasn't individuality or uniqueness of products that brought in the money....It was being able to make a lot of the exact same products. And when this became the general rule, then ALL manufacturing started doing it and everything kinda became the same -based on a price point.
I can't tell a new Toyota from a new Chevy anymore, but I can still tell a Ludwig from a Rogers!
