The day will come when either....
...all the so-called "psychedelic" oyster finishes will command riDICulous money...(WHY? Because those finishes are not only rare, but they also represent the look of the psychedelia that was omnipresent in those days. I'm talking about those old stage light shows with the oil blobs on an overhead projector...bell bottom pants....bare feet...hair parted down the middle...love-ins....happenings...trying to get the radio to play your TAPE...lol and it's all gone ....one day the people of that era will all be gone, too....but some of the representative relics of that time will live on...maybe only in museums... It was a time when even the musical instruments, themselves mirrored the look of the music they were making!)
OR....
...future generations will see drums in a less desirable/collectible/playable way and most will be discarded as junk. ;)
One of those just has to be right.....right?
I know times change as far as the two mounted toms sets go. I think it's because many drummers prefer to place a ride cymbal closer, in the space of that second tom. But, as far as vintage sets go, I'd always advise to disregard the fashion of the present in favor of the original configuration. So what if people these days don't prefer the two up configuration? There's plenty of people who have a thousand other options to use whatever they want. But what you have is a collectible item -something made to meet the needs and demands of the drummers of that bygone era. It is what it it....er...was.
Too bad the chemicals in the dyes they used faded so much. When you see an unfaded example, it's just....um....mind-blowing, man! ;)
