Okay...maybe I didn't find my answer!! LOL! Always ask the experts here first!!!!
Anyway, I purchased a 1960 Ludwig Pioneer 5x14 snare in a mahogany finish. It has the transitional Keystone badge with the blue lettering as well as nickel plated brass rims. It also has a nickel plated strainer and butt plate..both labled WFL.
There is also the date "Sept 21 1960" stamped inside the shell.
However, the snare lacks an internal tone control. In fact, there are no holes in the shell for one!
So my question is, did Ludwig not install tone controls on this snare during that transition period? Or if they did, is it possible this drum is a "fluke" and was missed when drilling?
