I assume you're concerned with tonal detriment, rather than difference here.

Others, like a M&H A, I installed vertical hitches and eliminated the bearing bar altogether. Again, with no problem. The Mason with the vertical hitches seems to have a longer sustain in the treble because the back scale in the high tenor rings longer, but I don't consider that to be a tonal detriment. Some might, in which case braiding a few unisons further up would have taken care of it. Ron N
