On thing I always noticed about mariachi bands in the San Diego area is that the smallest guy invariably gets the acoustic bass. (I'm sure it has a proper Mexican Spanish name, which I do not know...)
Correction, the smallest guy with the biggest stomach.
Its a Guitarrón.
There is no way this is restricted to my scene.
Everytime a group of people head to the stage and one of them is in a stupid hat... bassist. 10 times out of 10.
It is less common in metal... because hats aren't metal...
Metal bass players are almost always sporting a beanie, sorry... knit cap.
