The bass is also becoming “thumpy”. Granted, they are very heavily used (Up to 17 hours a day), but we try to keep them voiced and regulated so I don’t believe maintenance is the issue; I think the strings are simply fatigued. (I can break strings myself with 20 – 30 good solid blows.) I tried decreasing the blow to give a bit less power hoping that it would diminish the breakage, and that helps somewhat, but I don’t like to sabotage piano performance just so I can work less… BTW, the strings break mainly at the v-bar.<o:p></o:p> <o:p> </o:p> I will be restringing these pianos next month (I’ve HAD IT with them…) so does anyone have any advice concerning the scaling, etc.? I will be dressing the V-bar and doing all the usual prepping. This is a high tension scale and I’d love to redesign it but don’t want to put that kind of time and money into these…<o:p></o:p> <o:p> </o:p> Any helps out there???<o:p></o:p> <o:p> </o:p> Thanks.<o:p></o:p> <o:p> </o:p> Jim Busby BYU<o:p></o:p> </div> </body> </html>
