Using your Cort CPEG100 gig bag is a breeze. First, unzip the main compartment and gently place your Cort electric guitar inside. Make sure it fits well in the padded interior. You can use the two external pockets to store things like picks, strings, or a small tuner. When you're done using it, zip it up and store it in a dry place. Avoid leaving it in direct sunlight for long periods as it might damage the sponge lining. To clean it, you can use a soft, damp cloth to wipe the exterior. If there are any tough stains, use a mild detergent. Just don't soak the bag, as it could affect its structure.
