I am not a very good hobbiest. I have played instruments ranging from mandolin to an Azola Baby bass and a bunch of instruments in between. I have never known what the string spacing, fingerboard radius, nut or bridge width and in many cases didn’t know what the scale length or weight was. I am starting to get the feeling that I am not the most nuanced person in the world. I think that I should join or start a support group for people like me, that is if there are actually others like me.
