This is  100+ y/o building with</div> <div>the parish hall below the sanctuary, wooden floors. Again, the tuning took extra</div> <div>time while the piano acclimated.</div> <div><br></div> <div>It must be the radiant heat rising from below and is trapped within the full cover.</div> <div>I think this cover has the opposite affect of what is desired. I have recommended</div> <div>replacing the full cover with a string cover because of all the pianos I tune with</div> <div>standard covers or string covers, there is not such a drastic change in environment</div> <div>and their piano didn't exhibit pitch stability as one would expect.</div> <div>Besides, it's big, bulky and weighs a ton.</div> <div><br></div> <div>I recommended a string cover because they maintain the temperature fairly well</div> <div>in the winter. A string cover can stay on, providing it's insulating purpose through</div> <div>services and maybe performances and not experience such a change when removed.</div> <div>Also, the music people are not happy having to handle a heavy cover and would more enjoy the appearance of the piano without it.</div> <div><br></div> <div>Anyone interested in a full cover for a Bosey Imp?</div> <x-sigsep><pre>-- </pre></x-sigsep> <div><br> Regards,<br> <br> Jon Page</div> </body> </html>
