This baritone saxophone was specially ordered for this listing. It uses phosphor bronze brass (phosphor bronze), also known as "red bell," which is used in vintage Crampon S1 Prestige and Yanagisawa WO2 series instruments, for the body material. The finger buttons are made of resin that imitates black mother-of-pearl. In addition, the peg seat, which would normally be present, has been removed to reduce weight. The thumb rest and thumb hook are made of brass. The keywork adopts the Yamaha type from the perspective of having a double low octave hole and the most robust low-note interlocking system. (Selmer type and Yanagisawa type are also available) This custom-made baritone saxophone, with attention to detail, produces a rich, thick, and warm sound. When purchased, it will be fully adjusted, and an excessively sturdy hard case (with casters) will be included. Material: Phosphor bronze brass Finish: Clear lacquer finish Keys: Black mother-of-pearl style resin, Yamaha type, with High F#, front F, Low A system, double octave hole Tone holes: Partially soldered Thumb: Brass Peg: None Case: Hard case (with casters) In the past, Chinese-made wind instruments were said to be unusable and not produce sound, but in recent years, manufacturing technology and machining precision have improved, and they have come to have a certain level of functionality. I select "usable" instruments through direct negotiation with local factory craftsmen and dealers. Furthermore, after they arrive in my hands, I make detailed adjustments myself to optimize the instrument as a "tool" and achieve a low price.
