Hi David Thanks for the very topical and level response. If this is your evaluation, and it seems by and large most agreeable to my mind, then I'd have to go with defining such an installation as clearly a custom modification, and it should be so marked on the instrument in an appropriately visible yet modest fashion. And again I'd personally insist on such a marking if it was me doing the work if for no other reason then to insure everyone looking at the piano knew it was ME who deserves the credit for the pianos performance.... for better or worse :) The discussion as it tangents off in the direction of what real response differences there are (or are not) between the differing types of boards then need not be addressed further here. Thats a can of worms anyways and as you say... difficult to objectify anyways. But for clarification, variances in SB response between like construction methods board and general variance between different construction methods boards are two different things. I will without further ado grant the RC&S camp that that method is more predictable, easier to achieve and (apparently at this point at any rate) more stable over time. I guard that last point as we have'nt seen a surviving 100 year old example of these yet... nor a 25 year old one for that matter.... to my knowledge that is. Whether the observed variances in S&S boards are a desirable or not to the degree some think (either way for that matter) is a subject that dips quickly way to far into areas that are too subjective in nature to really debate constructively IMHO. It never ceases to amaze me what kinds of piano sounds an astounding number of people from all levels of music life seem to fall for. There is where I fall back on "live and let live" if you get my meaning. Cheers RicB For the record I would not say that one creates the same panel using CC or RC&S methods. Differences in each style's response to changes in humidity and issues of predictability, stability and longevity are differences and important ones. In terms of whether a CC board produces a different tonal quality than an RC&S board that's a more difficult question to answer because you have to ask against which particular CC board you are comparing it with. However, considering the number of original NY Steinways both new and old that I work on and the variation in tonal response due to soundboard differences that I hear (I think I can identify when tonal differences are soundboard driven as opposed to hammer driven), and compare that with the number of RC&S boards that I have now done, I would argue that my experience suggests that the range of tonal response that you find between pianos with original executions is far greater than any detectable differences between the RC&S boards that I do and the original Steinway pianos that I consider functioning with a healthy soundboard. That's putting aside small changes that I may make to smooth scaling transitions and enhance treble response and the like. I'm speaking more to the general tonal impression. Moreover, I would definitely say that the range in tonal response between the boards that I've done using RC&S methods is significantly narrower than the range I hear between soundboards with original executions and that would be true whether you are comparing a bunch of new ones against each other and/or a mixture of newer and older ones and/or rebuilt ones using original methods. I don't really want to get into the explanation about positive and negative springs and such because I'm not really sure exactly what you are saying but I have done enough RC&S boards now and heard enough disappointing original executions to be convinced that the RC&S method is a more reliable and more stable one. Are there fundamental tonal differences? For the sake of argument I would be willing to stipulate that there are though I would be hard pressed to identify exactly what those differences are. Nor would I say that they are significant enough for me to abandon the RC&S method in favor of the CC method that tends to produce outcomes with much greater variability than any perceived difference between the two methods. That, at least, is my own personal experience and as I continue to engage in these RC&S executions the evidence continues to mount in their favor. David Love www.davidlovepianos.com
