Summary: Low-quality build, poor tuning stability/voicing
Like Nordiska, Petrof, and others before them, Estonia appears to be one of the latest examples of a piano brand being sold based on their past rather than current production.
That they are never found in established, respected dealerships is the first red flag. They are reportedly one of the highest profit margin piano brands in the world. Unfortunately, being outrageously profitable does not translate to quality.
Another is the warning in The Piano Book that “the tuning pins be checked by a technician for proper torque (tightness) before purchase and that appropriate measures be taken to keep an adequate and stable humidity level where the piano is located.” We cannot find another example of this ever being recommended for any other piano brand.
The use of birch rims and Delignit pinblocks, and that they do not utilize industry-standard radial bracing may explain their reported lack of stability.
These pianos can sound ok in a showroom, but the combination of low-quality materials and designs lead us to question their overall stability and longevity. Out of our concerns about lack of endurance, we do not purchase or resell any new or used Estonia pianos.
