For sale: a 41mm silver-plated LeafLek. This item enhances volume and resonance, and you'll likely notice a significant difference when using it. The principle is to set it between the mouthpiece and the instrument body to efficiently return escaping vibrations back into the instrument. There are no scratches or dents, and it's in beautiful condition. Comes with the original box and one type of rubber band. I used it with a tenor saxophone. I'm selling this because I switched to a JLV phonique ring for my tenor. The 41mm LeafLek is a size that can be used with alto saxophones, tenor saxophones, baritone saxophones, trombones, and euphoniums (the rubber band size may vary slightly depending on the instrument). These are trading for around 11,000 yen, so please refrain from price negotiations. The current retail price for the 41mm silver-plated version is 19,500 yen, so this is a great deal.
