Experience superior studio-grade sound with the TreeWorks HS10 10" triangle. Made of hard, high-carbon steel that has been tempered to 500°F, the HS10 provides full-spectrum sound with a brilliant, shimmering response. Its graduated diameter makes each larger triangle sound better, and its ultra-thin zinc surface preserves its natural alloy sound. Hand-checked and bent for quality assurance, this triangle also comes with a wooden holder and 8" professional beater.
