※ Information regarding price negotiations is stated in my profile. Please take a moment to review it beforehand. This is a J. Michael euphonium. It uses a large shank mouthpiece (thick tube). In addition to the instrument itself, the following items are included: ・Mouthpiece (no brand. Included as a bonus) ・Semi-hard case (for transport. Zipper is broken) There is no model number on the instrument body, but I believe it is probably an EU-1500. It is a large shank, non-compensating, side-action 4-valve piston euphonium, and I believe it was designed with the YAMAHA YEP-621 in mind. It is made in China, and the finish is rough. There are also discolorations and dents due to age and use, and it shows significant signs of wear. However, there are no defects, and I believe it can be played without any problems. The sound is surprisingly good. I think the intonation is within a controllable range, but it's not easy to play, so I personally don't recommend it for beginners. I think it's more suitable for experienced musicians who want a sub-instrument or want to try playing the euphonium. For the listing, I have cleaned the inside of the tubes with cleaner and neutral detergent. I have also disassembled and cleaned all the parts. After cleaning, I have greased it and confirmed that it produces sound, so you should be able to use it immediately. I believe this is a product that has no problems with playing, but it is a used item, so please make your judgment based on the photos and consider purchasing. Please note that I am also selling this on other platforms. I will give priority to the person who purchases it first, so please be aware of this.
