<html> <blockquote type=cite class=cite cite>I have played and serviced SSDs that have a rich deep sound in the bass section and others that don't.  New hammers (cold or hot pressed) don't seem to change the situation.  Am I missing something? Tim Coates Wapin Co., LLP</blockquote> Hi Tim,             I have changed the bass strings, with a set of custom wound strings with excellent results.  If we are not looking at the board.  That's the other variable. Big variations in tone from note to note, with a new set of hammers is usually a tip off, that the strings are less than what they should be. I some times think the string winder puts too much tension on the winding. Regards Roger </html>
