<html> <body> Jim, If it is thumpy, have you considered adding some impedence?

I’m not sure if this made much of a difference, but the break does seem to be smoother and the bichords seem to have a slightly stronger fundamental. </ol>  A side by side listen with the same model showed vast improvements in the plain wire sections. I think this was mainly due to the stainless wire. Also, it tunes like a dream now! Removing the bump was easy and well worth it.   Although the piano is improved, in some ways greatly, I still don’t like the bass. It’s better than the old design but still a bit “thumpy”. Any feedback??   I attached a “before” picture and a close up of the bridge changes. The “bump” area looks like the new 1098s so I didn’t take a picture of that.   I highly recommend the “bump” removal and the Pure Sound wire. Jury’s still out on the other changes.   Regards,   Jim Busby BYU _______________________________________________ caut list info: <a href="https://www.moypiano.com/resources/#archives" eudora="autourl"> https://www.moypiano.com/resources/#archives</a></blockquote></body> </html>
