<html> <body> Hi Bruce,                  Start by muting all the un damped strings, and the back scale in this area.  A better than even chance it will disappear. I have some Sand bags that I can loan you. Regards roger.

We changed the bass strings to GC Piano Co. strings because the client was complaining about obnoxious overtones. Many of the offending overtones are still there.   Any suggestions as to how I might go about eliminating them, or at very least reducing them. I've tried voicing the hammers...with not audible change.   Look forward to your input.   Thank you.   Bruce</blockquote></body> </html>
