While I know it’s true that the primary purpose of my guitar case is to protect my guitar, sometimes it seems that it serves to fulfill a more important role: providing pockets and compartments for my guitar equipment.
Some of the guitar equipment is small and light while some is bulky. Some is cheap while some is a bit more expensive. Some guitar equipment I use each time I open my case and some are there for a rainy day.
Regardless of how often I use this guitar e, however, I have never regretted having them available at that critical moment when I needed it.
