I started playing drums back in like 1961 maybe, anyway, I have NEVER mixed brands of cymbals, never. I have two Sabian Ed Thigpen Crystal cymbals, one is a flat with a three rivet cluster and the other is a Crystal Ride which looks like the Sound Control pies with the flanged edge. I have never found a set of Sabian hats I like or crash(s). However I have a 16" A Thin Crash Zildjian with rivets and a set of 14" A Light hats that I love and so at this late date, I'm mixing them. What the hell! I know it is done all the time, but I would just like to have some reassurance that the world will not end because of my "transgression".
