The BC20 is a traditional Buffet Crampon model predating the R13, and it's no longer available. It features the "third bore" structure, which served as the foundation for the recently released Legend, Tradition, and GALA models. With a playing feel and sound quality that falls between the R13 and RC, it's easy to see why its sound is still sought after today, leading to its revival. Why not experience the history of Buffet Crampon firsthand? This instrument has undergone a complete pad replacement, utilizing the renowned kangaroo leather pads. These pads offer superior airtightness, durability, and water resistance compared to traditional pads, making them a top-of-the-line choice. Condition: Kangaroo leather pad replacement, complete cork replacement, body oiling, key polishing, includes case, pouch, and shoulder strap. Please contact us if you would like a mouthpiece.
