mysterious metal clips

[Robin Blankenship]

Thanks, Alan. Of course, I posted my query after spending a fair amount of time searching on the web and at the Archives and finding nothing. Then, right after sending my post, bam, there it was. I wonder if many folks are using these or not. And, what possible drawbacks there may be. 

Thanks again,
Robin

  Go to this website and you'll see pictures of your little clips ...

  These are often exhibited and classes given on their use at PTG conventions and regional seminars.

  Greetings all,

  I was recently tuning a Kawai GE-1A and noticed that three bass bichords had small metal clips attached to and connecting both strings in front of the agraffes. I do not believe I have ever seen this before. >From their size and shape, it was obvious that their placement was intentional and not the result of some rather odd looking staples or something falling into the piano. They would slide easily enough along the strings but were gripping the strings with enough force to prevent easy removal. I found little or no effect in tone or phase when I moved them back and forth a bit on the strings. Only three notes had these "clips". 

  If anyone here is familiar with this, would you kindly post a reply???

  Thanks, one and all.
