I am regulating a 10 year old Steinway M with all original action parts. I am having a problem with checking. The piano checks 100% on the bench, but no checking at all in the bass section and 85% OK in all other sections. I have adjusted the angle on the backchecks with no success. Does anyone have any thoughts on what the problem my be and a possible fix? Al Guecia -------------- next part -------------- An HTML attachment was scrubbed...
