The YUS1 is a premium instrument constructed from high-grade materials by master craftsmen. The hammers and strings are adapted from those found in the top-of-the-range SU7. The smallest of the SU series, this piano is perfect for the pianist who is short on space. Its superior build quality results in a rich, yet balanced tone. In terms of design, Yamaha has gone into incredible detail to make sure that this is one of the finest uprights they have ever created; with a soft closing fallboard and double casters for ease of use.
