This is a J. Michael euphonium, model EU-1500. I purchased it in March 2020 and used it daily for practice and recording until around April 2021, after which it was put away due to moving, etc. Wind instruments come alive when you blow into them. Please take it over. In addition to the instrument itself, the main items included are: ・Mouthpiece (no brand) ・Semi-hard case (for transport. Zippers and rollers are in good working order) The model number EU-1500 and the J. Michael engraving are on the body. Large shank, non-compensating, 4-piston side action. Manufacturer: J. Michael (EU-1500) Suggested Retail Price: 198,000 yen (including tax) Amazon Selling Price (Reference): 146,000 yen (including tax) Key: B♭ Valve System: 4 pistons (side action) Bell Size: Approximately 280mm Set Contents: Semi-hard case, cleaning rod Mouthpiece (large shank), instruction manual, gauze, cleaning cloth, valve oil (in use), slide grease (in use) For the sale, I disassembled the parts and cleaned the inside of the tubes with warm water and dried them. Only the first slide did not come out, so it remains as is. After cleaning, I greased it, oiled it, and checked the sound, so I think you can use it immediately. The valve action is smooth. Although not very noticeable at first glance, there are stains on the joints of the tubes on the body. I believe this is a product that does not have any problems with playing, but it is a used item, so please judge from the photos and consider it. Thank you for reading this far. I would like to ask those who will inherit it. We are very sorry, but we cannot accept cancellations or returns after the sale is completed. Thank you for your understanding.
