This will be a short review. Good and short because I really am impressed with these heads. I play at least three nights a week with a big rock and soul band named FreeWorld on Beale Street in Memphis and a good number of well-known drummers sit in on my drums. It’s a pretty hard-hitting gig and the guys that sit in don’t hold back. Though I prefer single ply heads on recording sessions and lighter gigs, I have used all sorts of two ply heads on my Gretsch drums over the years for the louder gigs. The two-ply heads last longer. They also all start denting up immediately and I’ll use each set as long as I can until they just won’t tune up anymore or are looking like the surface of the moon.
