You have had good advise here. What I would do is evaluate the scale and definitely rescale the bass. If there is a hook back on the treble bridge I may put two to six wound notes in the middle section if I can get substantial "improvement" by doing so. Changing the monochords to bichords is not likely to gain you much at all considering the amount of work involved. Yes, anything can be done, for enough money, but who gains what? Measure the speaking length of every note and the core and wrap diameters of several bass notes and I can tell you how to improve the scale. Don't try reinventing the wheel and some of those old guys KNEW what they were doing. Don't second guess old craftsmen. Newton
