I have no idea either. I have nothing conclusive to offer. My thinking regarding the plate and string height as a possible causal agent and the strike line is this: if the string height varies, but the hammer line doesn't, then the strike point for comparative notes will vary along the length of the speaking length, with attendant effects on the tone quality. That doesn't make it the cause, or even one among several. But it does qualify as my surmise as the cause, and nothing more than that is laid claim to. I do know who won the super bowl though.

I have no idea why, but it is pretty much a non-issue with an adequately built RC&S board with the same plate. This indicates to me that it's more likely the board than the plate. What would it indicate to you? Ron N
