Cluesman pianos are composed of 8372 excellent parts, all of which are made of top imported materials from all over the world.

They make them with the original data of European pianos at 1: 1, and make careful tuning and timbre arrangement for many times, ensuring that every single Cluesman piano is a unique work of art.
The ebony keyboard is adopted to ensure that the keys can be pressed by fingers with moderate strength. The technician strictly controls the springback load of keyboards according to industry standards, ensuring the sensitivity and reaction ability of keyboards. The whole keyboard undergoes advanced drying and moisture-proof treatment, so its sensitivity will not be affected by the change of air temperature.
Cluesman adopts the latest German soundboard suspension technology, and the soundboard is independently suspended around, which can improve the vibration effect of the soundboard.
The chord shaft plate is thickened, which strengthens the stability of the chord shaft, greatly prolongs its service life, and will not cause poor inflection. Solid back plate provides the piano better stability.
Rib strips with unequal
The bass area is made of thick and thick ribbed wood strips, and the middle and high notes are made of thin ribs. This design can make the soundboard fully resonate and ensure the best timbre.
German ROSLAU music wire
It adopts ROSLAU high-quality special steel wire imported from Germany, which ensures the professional effect of thick and powerful bass, smooth and pure mediant and bright and clear treble.
Only spruce that is mature enough can meet the making standards off Cluesman piano. The selected wood must have excellent elasticity and be treated with fine wood grain to ensure that it can show perfect timbre.
The process of setting string twist design is very complicated. Generally, only high-end pianos will be equipped with setting string twist design. It can increase the string length, so it is not easy to pronounce badly or incorrectly and the timbre is rather pure.
8-9 times of repeated timbre calibration
Every single Cluesman piano has to go through more than 8-9 times of fine tuning and timbre finishing before delivery, which properly ensures the golden timbre and intonation stability of the piano
