Sabian had the same logo from 1981 until 2019. It was the classic insignia of an iconic cymbal brand. They decided to modernize the logo and have it as a hand-drawn logo instead. Personally, I’m not a big fan of their new logo. Thankfully, it only appears on the bottom of the cymbals, so you don’t often see it! I know plenty of drummers who love it, though, so don’t let my opinion discourage you from getting Sabian cymbals. The logo has no effect on how they sound, and they sound incredible.
