Bach 180ML37SP Stradivarius Price: ¥561,000 This is a Bach Stradivarius model, a classic. The serial number is in the 390,000 range, indicating a period known for instruments with excellent resonance. This instrument also resonates beautifully and has performed well in performances. Both the pistons and slides operate smoothly without sticking. For the listing, the instrument was disassembled, cleaned, and greased at a musical instrument store. There are no noticeable major dents, and the condition is considered good. The tuning slide has been replaced with an Amado-type slide from M/K (worth ¥40,000), improving the playing feel. The bottom cap on the 3rd valve has been changed to a heavy type. The 3rd valve slide stop has been replaced with an Artisan one, making pitch adjustment easier. The piston buttons have been changed to custom specifications. With these customizations, I felt that it became easier to play a wider range of notes. There are minor scratches due to use. It will be shipped in a Bach original case. The case will be wrapped in cushioning material for shipping. Please understand that this is a used item before purchasing. Thank you for your consideration. ~~~~~~ bach Bach stradivarius Stradivarius 180ml 37sp artisan yamaha Yamaha
