The Hammond B3 weighs 425 pounds. Not a few roadies have almost met their untimely demise lugging this beast around from venue to venue.

Hammond C3. Sister to the B3, it is identical in every operational way to the B3. However, the C3 is even heavier as it has a more extensive wooden frame which surrounds the base of the organ.

This is a popular church organ. However, it has been noted that Bs are more available in America and Cs are easier to acquire in Europe.
