B-Stock units have either paint blemishes or some small scratching on the chassis.  These imperfections have come from the process of creating the chassis.  The chassis are made by hand and because of that, there are chances for human error to occur.  You can benefit from those minor errors as you get the exact same sound and build quality of an A-stock unit, but at a discounted price.
