The CB-AG10 is the ultimate soft bag for acoustic guitars. Boss is a Japanese company that produces high-quality accessories for the guitar. This bag was designed to offer the same protection as a hard case but with the versatility of a bag. This means that you do not have to worry about the bulk and weight of a hard case. Bags are generally less protective than hard cases, but this is not the case with the CB-AG10. The bag has three separate layers: a durable exterior layer, thick padding, and a soft lining. The bag can be carried by hand or as a backpack.
