I agree that rendering problems will not be resolved by the DC. However, rendering problems and their contribution to instability are much more pronounced when the piano is subject to larger pitch swings. Poor rendering doesn't mean that the piano can't achieve stability. It does mean that it's more difficult to tell when the piano achieves stability (as Ron mentioned). By keeping the piano as close to constant pitch as possible you will have a better chance of establishing some greater level of stability--no guarantees. I wouldn't necessarily try and sell a bill of goods with promises that can't be made, rather, I would outline the overall problem, various approaches from least cost (and least but possibly somewhat effective) to higher cost (with greater chance of being effective) and help them decide within the constraints of their budget now to proceed. My guess is that a full DC system will be needed to help with stability even if you go the restringing route so starting there and seeing if there is improvement will not be a waste should they decide (if it's financially possible) to go the more complete route. Explained in that way I think you would obviate the risk of them feeling like you sold them something that was unnecessary. On the flip side, if you sell them a restringing job and then decide that they need the DC system as well, they may feel that you sold them a larger job when all they needed was the DC system. Right or wrong, you may have a more difficult time explaining that in a convincing manner.

If the piano is played extensively - as in many hours a day, 5 days or more a week; the damp chaser may be ineffective. The reason I say this comes from my own experience as a tech here in the Northeast (New Hampshire) where we have long and cold winters and humid summers - generally a good set of conditions for recommending a d. c. unit. But a good teacher customer of mine comes to mind. She teaches 8 hours or more a day, so her Yamaha G-3 is open (at least the small lid) for probably close to half the day. There is simply too much free air moving through the piano for too long for the d. c. unit to keep it stable, and the control unit was not a good investment in her setting. Ron is right in that, if this is the case with her, she might end up thinking you sold her a bill of goods for good money that did nothing. It could worsen your relationship with her as a result. You may end up recommending restringing with the attendant bearing surfaces work. It would be my guess that this condition will only continue to worsen over time, along with an increase in your misery level and her frustration level. Sometimes we have to let the customer know that we can't give them what they want, but we can give them what they need. That's your selling job with her - to establish your credibility and clearly define the solution path. It is the customer's choice at that point to accept your diagnosis and path to correction, or look elsewhere. No apologies should be necessary or given - the piano is what it is.

I think it's past time to introduce her to reality. The string rendering problem means that you can't get enough information from the piano during tuning to leave it in a stable enough condition to be reliable. That's neither your fault, nor your problem. You're already giving it your best shot and picking up the pieces at your expense. Selling her a Dampp-Chaser system isn't going to help the rendering problem and won't be well received if it produces no improvement of the situation. Addressing the problem directly is, oddly enough, usually the best way to correct or at least improve it.The piano realistically needs work, likely extensive, to improve string rendering, with humidity control next on the list if it proves necessary. My call, Ron N
