Description
The Yamaha UX3 is a legendary 52″ professional upright built exclusively in Japan during the 1980s and never exported to the US market. Often called the “super U3,” the UX3 represents the pinnacle of Yamaha’s upright piano craftsmanship, designed for advanced players and institutions requiring concert-level performance in a compact format.
The defining feature is Yamaha’s patented X-bracing back post design, which provides exceptional structural integrity and tonal stability. This revolutionary construction allows the soundboard to vibrate more freely, producing richer, more powerful tone with enhanced sustain. The UX3 features extended bass strings (longer than the standard U3), premium hammer felt, and hand-selected soundboard spruce—materials typically reserved for Yamaha’s concert grand pianos.
Handcrafted by Yamaha’s most senior technicians, the UX3 delivers grand piano-like tonal depth, responsiveness, and power. The three-section front panel design creates strategic air gaps that enhance sound projection and clarity. With soundboard area comparable to many baby grands, the UX3 offers professional performance that rivals much larger instruments.
Rare and highly sought-after by pianists and technicians worldwide. Available in polished ebony. Perfect for serious students, educators, and professional musicians.
