"for research purposes and I'll resell it when I'm finished with my analysis" is my phrasing.I blame forums.
I remember reading threads about how a particular snare drum sounded relative to another snare drum and thought, that doesn't make a lot of sense. So I'd buy two of the drums in question to hear the difference for myself. After a while I started buying snare drums to appease my own curiosity. I eventually ended up with thirty four snare drums. I did a major sell off and eventually had a manageable nine or so snares. Recently I came to the realization that the number of snare drums that I own has crept past twenty five again. Hmm. I'm not entirely sure how this happened this time.
No harm in looking. And yes, there are Sunday date stamps according to an analysis of these I did with data supplied by KCDrumDad.I was born on a Sunday in 1959. It would be very unlikely that I'd find anything built on my birthday. (If I were looking.) It is a fun idea though.
