- Guitar Strings.
String set your sound and how easy it is to play. As a beginner use lighter gauge strings, 8's or 9's as these are easier to play. The gauge is set by the width or size of the first e string. Easier to press down and bend. Also they give brighter sound. Try heavier gauges such as 10's and 12's once you are playing a while to see if you like them. They are harder to play (and harder to break) and give a heavier, darker, bassier sound while you might prefer. Also try different materials and alloys. I have liked Gibson Brite Lites myself. I like the feel and the sound of them.
Plectrums or picks also come in different sizes or widths and materials. You can get any size from 0.4mm, 0.6mm, 0.7mm so on up to 1mm and 1.2mm. I would recommend buying a range of picks as they are cheap to see which one you like.
They also come in hard or soft material, from plastic or nylon to metal. The material will give a different sound depending on the string attack (how you hit the string). Most people use plastic or nylon plecks although some lead guitarists use the metal picks.
I use 0.6mm Dunlop Nylon picks. Sometimes you might prefer as few different types depending of what guitar and style of playing you are at.
- Guitar Strap
You can get any strap you like as long as it is comfortable. Make it is wide enough that it will not cut into your shoulder. Softer material is also more comfortable but a wide leather strap can be okay too.
- Guitar Case
Get a guitar case if you are going to take your guitar outside. If you are going to carry if it a soft case is okay. A soft case can cost from $25 up. If you are transporting it on a plane or vehicle a hard case is really required to stop the guitar getting damaged. These are more expensive and should fit the shape of your guitar.
- Guitar Stand
I would recommend you get at least a cheap guitar stand for storing your guitar at home. You can get one for $25 which is a lot cheaper than having to buy a new guitar if it is damaged by falling. Also store it in a dry cool place, not beside a hot radiator.
That concludes the main items and accessories you may have to buy for your guitar.
