Hello, We service a 275cm Bösendorfer in a concert hall. It´s only eight years old but I have been noticing that the bass strings are very...timid. I´m scared stiff when I start going down the bass since the tunings are most often a few hours prior to the concert. The rendering starts being very awkward on the first bass string, and all the way down. The rest of the grand is fine. What would you recommend regarding lubrication? Protek? It has to look fine. I also thought that maybe this was a problem with the tuning pins being stiff but I´m afraid to pull them too hard. Any comments? Kristinn Leifsson, Reykjavík, Iceland
