Each Four Star Reconditioned Piano undergoes an extensive inspection and certification process to ensure optimal playability at an amazing price.
Cabinet buffed and polished to original luster. Brass hinges, pedals, and lock assembly cleaned and polished.
To insure tonal quality and stability, the soundboard is inspected for full structural integrity, proper adhesion of ribs, and absence of cracks. Bridges are inspected to ensure they are free from critical cracks. Bridge pins are inspected for proper side-bearing.
The downward pressure of the strings against the bridges is tested to ensure the proper soundboard crown, tone quality, and resonance.
To ensure tuning stability, the structural integrity of the pinblock is assured by testing the upward and downward torque of the tuning pins.
Tuning pins are found to be clean, free of corrosion, and of uniform size. Proper spacing between string coil and plate is ensured.
Strings are free of corrosion, rust, and damage from liquid intrusion.
Construction and geometry of the keybed are checked to ensure proper operation of the action.
Keys are removed and rail pins are individually inspected and cleaned. Worn punchings are replaced.
Keytops and keyfronts are cleaned or replaced as necessary to ensure uniform bright-white appearance.
Worn key bushings are replaced to ensure proper lateral tightness of the keys.
All pedal rods and trapwork are adjusted to ensure proper operation of the pedals. Worn felt bushings are replaced as necessary to ensure quiet operation.
Damper felt is inspected for proper hardness. Damper levers and wires are adjusted for proper and efficient operation.
Hammers are inspected and reshaped to attain the correct firmness and geometry, assuring full and proper contact with the string.
Operation of the flanges, center pins, and bushings are tested to ensure efficient and fluid motion of the hammer.
All components of the wippen assembly are inspected and adjusted as necessary to ensure efficiency of motion between the key and the hammer assembly.
Warn or degraded hammer return spring cords are replaced on Yamaha upright pianos to ensure proper note repetition and dexterity of the action.
Technicians clean and inspect the structural integrity of the sound plate.
The touchweight of each piano is adjusted to retain the lightness and agility that are the hallmarks of Yamaha and Kawai pianos while still allowing for a satisfying dynamic and expressive range.
The action is adjusted to ensure that each piano has a consistent, efficient, and expressive feel and touch in all registers of the instrument.
The tone quality of each piano is adjusted and perfected to reflect the clarity, brightness, crispness, depth of tone that is inherent in Yamaha and Kawai pianos.
The equilibrium moisture content (EMC) of the critical wood components of all pianos are carefully monitored to ensure compatibility with all North American climates. Soundboards are repeatedly tested and found to be at or near the recommended 7% for North American homes.

At the Yamaha lumber mill and wood processing facility, the finest spruce is quarter sawn; and less than 10% of the total is selected and reserved for Yamaha piano soundboards. Solid spruce, rather than laminated spruce or poplar, is the choice in all fine pianos for the best amplification of sound, best tone and sustain.
Full Length Ribs
Yamaha reinforces the crown in its soundboards by using ribs that continue to the edge of the soundboard, and are glued into the notched liner (or inner rim on the grand piano). Reinforcing the crown ensures that the tone quality will remain for years and years and improves tuning stability..
Metal Action Rails
Yamaha engineering developed a unique Extruded Aluminum Alloy Action Rail (bearing a Yamaha patent) that is one of the best innovations for improving a piano action in the last 100 years. The usual fluctuations in wood rails that effect touch, caused by periodic weather changes, are eliminated allowing stable, long-lasting action regulation.
Each key of a FourStar Factory Restored Yamaha piano is individually tested and measured for the corrections needed to obtain uniform "down weight" pressure. Yamaha actions play correctly and uniformly. This balancing helps ensure a lifetime of superior touch and control across the keyboard.
Uniform Key Travel
Yamaha designs all grand and vertical pianos to have the same key travel. Regardless of size, type or model of Yamaha piano, the keyboards will always feel the same.
Yamaha uses Spruce for the keys on all models of pianos. Spruce is very light and possesses a very high ratio of strength to weight. It is ideal for key construction, even though its cost is greater than either sugar pine or bass wood. Yamaha keyboards respond quickly providing fast repetition for the most intricate piece of music. Yamaha keyboards withstand heavy use over years of fortissimo passages.
