When it comes to the best cost-performance baritone mouthpiece, many professionals recommend this one. It's a Berg Larsen metal mouthpiece for baritone saxophone. The "105 1 M" font suggests it might be a vintage piece from before the offset era. It's one of many vintage mouthpieces we purchased. In any case, I believe it's quite old. Berg Larsen is a traditional mouthpiece loved by many famous players. Jazz giants like Pepper Adams are representative users. This mouthpiece is recommended for everyone from beginners to professionals. We will cover the shipping costs.
