I did alittle experiment and noticed that string cleaner for violins does a fabulous job!<BR>To my experience applying DAG and piano sounding richer isnt only with my own, I have done this before on a Mason & Hamlin, effect was similar. I have removed the strings in my piano off before and put them on and this effect hadn't taken place..<BR> <BR>Alicia<BR></DIV></BLOCKQUOTE></BODY></HTML>
