To be honest: it sounds absolutely normal. I would not have noticed that special bridge arrangement while tuning if I had not taken a look on the bridge.   Gregor ------------------------ piano technician - tuner - dealer Münster, Germany www.weldert.de   <div>> From: davidlovepianos@comcast.net > To: pianotech@ptg.org > Date: Thu, 25 Oct 2012 12:22:05 -0700 > Subject: [pianotech] Bridge agraffes FYI > > > Attached are two photos of a Sohmer Grand bridge with bridge agraffes.
