What does 000 mean in guitars?

000 / OM. Shallower than a dreadnought (see right) at around 105mm (4.1) and narrower in width, the 000 (also known as an auditorium) brings the body closer to the player. As theres not as much mass to curve your strumming arm around, it feels more intimate and comfortable for stage use too.
