Ahhh! Thanks for this Allan. The video's help explain it a lot better. Very well thought out device. Too bad he doesn't actually have an audio file that demonstrates the audible differences. Ben's observation that the end result sounds similar to an engaged upright practice mute rail is a good comparison. That's actually something I can demo to the customer. Thanks to all for the response on this question. Very helpful, indeed. -- Geoff .

The resulting sound is very nice, and very muffled. My client is happy. Steve is helpful with our questions. My client wanted still more damping power, so Steve provided a different material. I did the soldered installation but the new one should be easier. It's a good idea well implemented. Go for it ! http://www.grandpianomuffler.com <http://www.grandpianomuffler.com/> Allan Sutton, m.mus. RPT www.pianotechniquemontreal.com 2010/9/24 Ben Gac, RPT <ben at benspianotuning.com> Geoff, I haven't installed one, but I just sat through Steve Jame's demonstration at our chapter meeting last Tuesday. As I understand it, the system will take about 3 hours to install (maybe 4 for first timers) plus initial measuring. I believe his target for the technician is to make the Grand Piano Muffler cost about $500-600 for a client. It seems to me like he's got the system down pretty well now. No soldering is required anymore. For a retrofit mute rail, there's no better option--plus, unlike foam baffles, one can disengage the system with the pulling of a pin. As far as "deregulation," Steve recommends setting the let-off at just at/barely before the hammer strikes the felt. A little less power, a little less control. There's some compromise there, but it's necessary with any system that uses a mute rail. I heard the piano with the rail engaged and it certainly brought the sound down significantly. Of course, because the hammer is striking the felt over the strings, the clarity of attack is considerably muffled (hence the name, right?). I'd compare the sound to just about any upright with the mute rail installed; it's perhaps even a bit quieter. I'm sure Steve would be happy to answer any of your questions.

Has anyone here ever installed one? Does it work without forcing too much deregulation of the action? For that matter, does it work? I have a customer who only gets to play late at night and her neighbors are complaining. Perhaps some heavy foam underneath? I'm open to recommendations. -- Geoff .
