A hard case is the best way to protect your beautiful expensive guitar. Whether it be acoustic or electric, a hard case is going to provide the most protection against knocks and falls.
The most common types of hard guitar case are made from strong wood, with a leather finish, though some guitar cases are made out of ABS plastic. A velvet lining is usually found on the inside, to prevent damage to the guitar while in the case. In addition, hard cases will usually feature a utility compartment, to keep guitar leads, capos, tuners, and other guitar accessories.
