Hi,
I mostly agree with Jim on this.
Most of the instruments with these kinds of designs that I have seen
over the years have still been in medium to large acoustic environments;
and, to my ear, those that have been restored with the "staggered"
bridge pins as they were designed pretty much always "work" better than
ones in which the SL's have been equalized.
Anyway, while I'm sure that this one is going to thoroughly kicked
around the barnyard, I remain convinced that the folks who came up with
these designs knew precisely what they were doing; and, as Jim notes, in
the environments for which they were designed, the scales can work very,
very well.
Kind regards.
Horace
