Hi Tom, I would look carefully at the following: Not in any order. action regulation, not the gross aspects but the super fine areas of superlative regulation, check every regulation point. Pinning, general. Specific, jack, hammer, wippen, balancier. Touch weight; balance and friction weights first. Check for polished and lubricated front pins, no excess friction when forcing bushing against pin and moving key up and down. Damper timing. Listen to the tone, too bright, loud, soft, weak. Tuning. Remember customers often translate one problem into another, i.e., muddy tone - too hard to play. Take measurements, listen, play and then ask the customer to demonstrate their concerns. This has to be a collaboration of her perceptions and your skills. Go in with confidence, assurance, reassurance (this is after all is said and done, a machine) and a willingness to learn and cooperate. Don't make snap decisions or judgments. Think! Then plan an action and act on your thinking. You can do this. I have found, that generally, factory regulation falls way short of the piano's real potential. Go do good. Newton
