Well if you're only gonna have one kit, it's pretty damned easy to see why it would be this one. There's just something so iconic about WMP on an old classic set of drums like those. I love 'em too.....fabulous!!
I also had a Slingerland kit at the end of the seventies (still have the Gene Krupa snare). Despite the fact that I never was really satisfied with its sound (but I never really learned how to tune it ...), I always loved its look. And still like very much that classic Slingerland style!
Actually, there is another interesting video where Steve presents another incredible Slingerland set (copper over wood, like the one I owned a long time ago ...) and talks about Slingerland drums: http://www.youtube.com/watch?v=T0HTlKsznOY
I was to play another guy's kit at a jam session a few weeks ago. Not knowing what was waiting for me there I was ecstatic when I walked in to see a kit identical to yours, but with the matching wood snare and it was a 4 piece though, all in white marine pearl.
Afterwards I vowed to get one. It was hands down the sweetest kit I've ever played. Even nicer than my Ludwig club dates. I can see why it's been your only kit.
Sensational drums. I have a 1962, 13. 16, 20" kit with a late 60's Sound King. The Sound King is featured in my current thread. The kit is in deep storage as it is mint. There used to be a pic on my old Gear thread.
