This is a Yanagisawa WO-20 alto saxophone. Below is the description. Reference price for a new WO-20: ¥649,000. The WO-20 is made not of regular brass, but of bronze brass, which contains copper. While normally finished with gold lacquer, this particular instrument has a brushed satin gold plating (GP plating) on the U-tube and bell, and the inside of the tubing is also GP plated, with the interior being standard GP plating without satin finish. Furthermore, the connection between the U-tube and the body is soldered, making its responsiveness and sound projection incomparable to a standard WO-20. I actually compared it with a displayed, playable WO-20, and it was on another level. I'm not exaggerating; it's so easy to play that it makes you laugh, and the sound, with its bronze and GP finish, is warm, projects far, and is beautiful. It suits classical, pop, and jazz, but might not be ideal for flashy genres like fusion. If the entire instrument were GP plated with bronze and GP, it would be extremely heavy, demanding a lot from the player, and would be geared entirely towards classical music. However, by keeping the first branch in its standard finish and adding the soldering, it has been finished to achieve excellent versatility and projection. The neck is the standard WO-20 neck, but a GP-plated neck adjusted for this instrument is also available. Please inquire about the price. The last three photos show the GP neck as a reference. Please note that if you do not specify in the comments, only the standard neck will be included. As mentioned in the title, it has been fitted with "Shibata" screws. I couldn't find the normal screws, and I will include them if found before sale, but they are not currently included. There are no scratches that affect the instrument's performance or history of drops, but there are minor scuffs from normal use. Please understand this point. When purchased new, it underwent a complete overhaul, during which the GP plating and soldering were done. I don't know the current cost of doing the same thing due to gold prices, but it would probably be around ¥500,000. It was recently fully adjusted by a renowned workshop and is in perfect condition. I don't expect maintenance costs for some time. I bought it for a family member, but due to circumstances, they can no longer play it, and since I primarily play tenor, I've decided to sell it. I am open to questions. Thank you. The case is a Protec flight case. It has ample storage and is a good case.
