Marcel. I am not qualified to comment about pressure ridges, but I would suggest you inform the school of the problem before the piano leaves the school. Give them?all the options, and even if they opt not to do anything to the soundboard, you'll have covered your rear end.

Now they want me to do it next summer. I serviced the piano yesterday and noticed an impressive pressure ridge that runs in front of the treble bridge from the tail to the treble end. Now what annoys me is that I'm afraid that after restringing what if the ridge cracks open? The piano is about 20 some years old in a college situation with a Dampp Chaser installed, but not always plugged in... Would there be anything that I could do once the strings are off to get rid of this ridge, should I stay away from this job? I'm not sure I could sell a new board (no money-no candy). Maybe some of you could give me your thoughts on this. Thanks, Marcel Carey, Sherbrooke, QC = -------------- next part -------------- An HTML attachment was scrubbed...
