This piano is a full size upright from the premium line of the Ritmuller brand. It is one year old and in 100% perfect condition. I believe it is better than new, because with regular servicing over the past 12 months the tuning is stable and the voicing is refined.
Its components include a solid spruce sound board, Renner hammers and German Roslau strings. It has a warm upper register and powerful bass.
Many experts say the tone is superior to Yamaha. Search the model name youtube for demonstration, and the Piano Buyer's Guide for reviews.
These pianos sell for around $8,500 brand new, and I am suggesting $6,000 is a good price for this nearly new one, with no taxes to pay either. I have the original bill of sale for you to inspect.
