The Yamaha UX10A is a high‑end upright piano from Yamaha’s UX series, representing an upgraded version of the already respected U10BL and U10A models. 
🛠 Key Characteristics
Premium Build – Made in Japan (late 1980s–early 1990s), known for high‑quality materials and solid craftsmanship. 
X‑Braced Back – The UX series uses an X‑brace internal design, which adds extra structural strength and potential tonal benefits compared to standard straight‑brace uprights. 
Sound & Action – Often considered to offer richer tone, better bass resonance, and more refined action than many standard models
