<html> <body> Robert, I've seen all kinds of answers to your question. Why not just put your temperament strip into the end of your rubber mute? Even if it does fall, it's easy to get out!!!!

In some places it is difficult to find the best position to place the mutes, especially in the higher treble because the strings are so short and there is so little room. When the mute falls down it sometimes dislodges the hammer butt springs and I have to re-position them on the hammer butts with a damper regulating tool. What would you recommend I do to stop this happening? Thank you very much.   Robert Finley</blockquote></body> </html>
