Who uses them or have heard someone use them personally (not A. Spears). I banged on one at a jam session last night on a 14x6" aluminum snare and it sounded ok it wasnt the best thing I ever heard but I mean it cut out all overtones that snare could have possibly had. But, I want to know has anyone tried then on another size snare like a 13 or on another type of metal or wood??
