<div> <font face="Arial, Helvetica, sans-serif">Thanks, William.  I've seen that system on the better installations.<br> <br> Another thing: in order to accommodate the solenoid cutouts in the back of the keybed, one or two of the keyframe guides are usually removed.  On a couple of pianos I service, I'm having a devil of a time bedding the keyframe so the front rail doesn't knock without there being a squeak/creak/groan from the back end of the frame when operating the una corda peda.  This seems to be related to the missing guides.  Any suggestions on this one would be welcome.<br> </font></div> <div> <br> </div> <div id="sig9894" style="clear: both;"><font>Dave Stahl, RPT<br> Dave Stahl Piano Service<br> dstahlpiano@sbcglobal.net<br> dstahlpiano.net</font></div> <div> <br> </div> <div> <br> </div> -----Original Message-----<br> From: William Monroe <pianotech@a440piano.net><br> To: Pianotech List <pianotech@ptg.org><br> Sent: Wed, 24 Sep 2008 6:12 am<br> Subject: Re: Digital players in high end pianos<br> <br> <div id="AOLMsgPart_2_1ef897aa-71b0-47b5-951a-7b5e9b5cc793"> <div><font size="2" face="Bookman Old Style">HI Dave,</font></div> <div><font size="2" face="Bookman Old Style"></font> </div> <div><font size="2" face="Bookman Old Style">I share your discontent.  Mostly from the perspective of people and their passionless things.  It is tragic.</font></div> <div><font size="2" face="Bookman Old Style"></font> </div> <div><font size="2" face="Bookman Old Style">Re: the QRS system, one thing I've found to improve pedal performance dramatically is to take a coil spring and cut it to an appropriate length to fit under the damper pedal trapwork, just in front of (or behind, if there isn't room) the pitman.  This does wonders to restore the usefulness/normalcy of the damper pedal function.</font></div> <div><font size="2" face="Bookman Old Style"></font> </div> <div><font size="2" face="Bookman Old Style">William R.
