This is just curiosity about something that I've always wondered about and now that Michael Watts posted the video below I feel compelled to ask ...
I find that a rather surprising advice coming from him if not only because he claims the shape to be comfortable while AFAIK he's said the opposite about regular dreads.
But that just adds to my interrogations: is there more that's different in these guitars than just the round-off radius of the shoulders? Could it be that we hear the rounder voice with our eyes ... or that we actually hear a different voicing with the shoulder shape mostly a visual label?
(The shoulder shape thing always also reminds me of a
user interface design aspect ...)
