Having the right guitar cases for your guitar instruments is one of the better investments you’ll make as a musician. Not only do they keep your beloved guitar protected from damage and the elements, they make it easier for you to transport your guitar and a few essential pieces of hardware, such as a cord, some picks and guitar pedals.
Choosing the right guitar cases will depend on the shape and quality of your guitar. For instance, acoustic guitar cases will require a totally different width, shape and thickness than electric guitar cases will. The acoustic guitar is especially susceptible to the elements, such as dust, dirt and moisture, so it is more of a definite need to keep these types of guitars protected.
Bass guitar cases are going to be longer that standard cases because of the increased length of the neck on these instruments. They still come in various shapes and thicknesses, which is another aspect to consider.
The shape of most guitar cases will be rectangular, general guitar shaped or actually fitted to a specific guitar. The value of your instrument will most likely determine which style of guitar case is right for you. Soft cases are most often enough for beginner guitarists who are on a budget and have entry-level guitars. A soft case has a little bit of padding and usually has a number of pockets for storage of smaller items. They also come with a shoulder strap and can sometimes come with 2 shoulder straps that turn the bag into a backpack. Backpack guitar cases are especially popular with younger guitarists and really make transporting their gear easy and hands-free.
Guitar hard cases are a lot more durable than the soft ones and they do a much better job of protecting your guitar. They are normally lined with foam or a velvet material that will not scratch your instrument. Hard cases that are rectangle shaped will house most electric guitars but will almost always leave room for the guitar to slide side to side. On the other hand, shaped guitar cases will fit your instrument perfectly and will hold it in place with no room to move around.
You want to make sure your guitar case will have a storage compartment inside to store your smaller necessity items. This comes in really handy for heading out to quick jam sessions or for just having the piece of mind that your necessities will always be in one place with your guitar.
The price of guitar cases can range from a $20 for a cheap soft case, all the way up to a few hundred dollars for a custom hard case but are really one of those musical instrument accessories that you shouldn't go without. Make sure to take your guitar with you so you can try it out in a few different cases before you purchase one. I once made the mistake of buying a case that was on sale with no return policy without trying my guitar in it. Live and learn because when I got it home, my guitar did not fit. Don’t make this mistake
