I honestly don't see any deep and meaningful value in the drums. There was no VINTAGE vibe during the 40s, 50s, 60s, or 70s. I'm speaking en masse. It wasn't until the late 80s and 90s before it hit fairly big. Now, it's become a joke. Every spoon billed gull jockey believes they can make a mint on anything that could be connected to the drums during those time periods.
The proof is everywhere you care to glance.
Numbered COLLECTIBLE snares, Retro Wraps, Rereleased cymbals, Vintage Modern Kits, blah blah blah. Not to mention Marvin and Helgas Vintage eBay store run out of their trailer shed. What a crock.
Once the product is defined for the society, redefining is not an option. An entirely new market must be developed.
Vintage Drums has been defined. That's pretty much that. Oh sure, there will always be the fringe explorers, but by and large, it's done. There will not be a 90s vintage kit bidding war and collectable game for the vast majority of us. Those drums are out of bounds for our little game.
There will always be a market for well built instruments. But, that's a different set of rules.
