We are talking about a complex termination here, with the string contact on both the surface of the bridge at a tangent point to the diameter of the string and on the pin at a position above the bridge plane depending on the gauge of wire and angle of pin. To say that the pin depth has nothing to do with energy transfer is totally counterintuitive. And it is an impedance concern; any analysis of the Wapin structure would lead to impedance concerns. What exactly impedance concerns, I can't say for sure yet, nor can they, but obviously the decoupling effect of changing the angle of the bridge pin and having a higher contact point on the pin with the string is causing a sustain change, read impedance effect. To clarify myself (like butter?) a bit more, I don't think we're talking about huge energy concerns here; minute ones at best, but still energy transfer. Aside from intuition, my real experience has been that deeply driven, bottomed, and least expose pin top structures have greater clarity of tone production than any with these and other variables not in evidence. I can only go on what experience has been proving to me time and time again as we try to get better at what we do. As far as the unsatisfactory nature of intuition, I can't say. :) PR-J
