Installing a set of new hammers

Adding a new set of hammers to an older piano will give a nicer sound and a longer life.  If your piano sounds "harsh" or "too bright", that could mean the hammers need to be voiced or reshaped.  If the hammers still feel hard, it might be time to replace them.
New hammers will give the piano a warm, more pleasant sound.  Along with giving you a new motivation to play alittle more.
