Paul, the customer should understand that putting on a non-lacquered type hammer (i.e. a high tension hammer like Renner) will completely change the sound of the instrument. If he is happy with the general sound of the instrument right now, then choose a low tension hammer to replace what is currently on the piano (Ronsen makes a great Steinway substitute). However, the hammer choice will in and of itself will not improve any of the power issues. Bradley M. Snook Rice University Shepherd School of Music
