<< I have done all I think possible with hammer voicing to even it out. I'm thinking it is a board/bridge/string issue of mass (too much or too little?). Or impedance? Or, ??? Short of board re-design, anyone have any suggestions for improving this transition? >> Greetings, Have you taken a small set of vise-grips and attached them in various places on the bridge pins? Somtimes, adding that amount of weight in the fifth octave will greatly improve sustain as well as tonal depth. It is easy, cheap, and removeable to find a spot that makes an improvement and then screw that amount of weight into the bridge from below the soundboard.
