One way is to needle the hammers of your instrument. When the hammers are too compacted, they cause the production of harsh tones. The needle tool consists of needles that are inserted into the hammers. Therefore, the needles act by reducing the hammers compactness.

Another proven and useful way to fine-tune the sound of your digital piano is through the use of chemical solutions. There is both a hardener and softener solution to service the hammers, with the results being clearer and brilliant tones.

However, take caution with this procedure as too much of the solution can end up causing damage in the future.

Proper maintenance and care for your instrument is a crucial factor to consider. It ensures that the lifespan of the piano increases, as well as the sound including other important factors.
