Thank you for viewing. This is an F main tuning slide for the Alexander 103 (yellow brass, non-lacquer finish). I purchased this this month and used it a few times, but the tuning slide I received from a friend suited me better, so I am offering this one for sale. The playing experience gives the impression of a wider sweet spot, allowing you to blow with confidence. Also, you can feel many overtones, resulting in a very rich sound. As there are individual differences in instruments and tubing, please arrange for adjustments after purchase. Purchase price: 40,000 yen ⭐︎I am also selling this on other flea market sites, so please let me know in the comments before purchasing. Thank you for your consideration.
