You're welcome Ric, I concur to say you regulate more power/sustain balance there. The stiffening of the board helps to support the killer zone a tad indeed. I noticed that if the crown was noticeabley higher with the turnbuckle tensionned a lot (I obtained a rise of 4/10mm) the tone was not really better, so the pressure may not be extreme , it is regulated like the tulip screws, a very little after initial tensionning. But the effect is more than simple accoustical coupling I'd say. Best regards. Isaac OLEG Isaac OLEG Entretien et reparation de pianos.
