There’s a reason why the vintage Brilhart 3-Band ligatures have been singled out by the market (players) as by far the most desirable vintage ligatures. They are great ligatures. But there will never be enough vintage Brilhart ligatures to meet the high demand for this style of ligature. Thankfully, there is now a high-quality, hand made reproduction available to meet this demand. These are made by a small company in South Korea that cares about getting saxophone equipment right. These ligatures get rave reviews by the people who buy them. I don’t want to make huge claims for a ligature, but I will say that people tend to LOVE them. They’re beautiful, simple, and easy to use, and they sound great.
