There's no other instrument with as much presence and cultural identity as the guitar. Virtually everyone is familiar with tons of different guitar sounds, from intense metal shredding to soft and jaunty acoustic folk music. And behind all those iconic guitar tones are great sets of strings. Just like a saxophonist changes reeds from time to time or a drummer replaces sticks, putting new strings on your guitar every so often is an important part of owning and playing one.
The two most common types of acoustic guitar are the steel-string guitar and the classical guitar. The classical guitar, also known as the Spanish guitar, usually uses nylon strings. Steel-string guitars originated in the United States and are also referred to as western guitar and folk guitar. Steel-string guitars sound louder and brighter than classical guitars, which have a warmer, mellower sound. Steel-string models usually have larger bodies and narrower necks, and they often have a pickguard to protect the body against scratches by picks and fingernails. Most acoustic guitars have six strings, but there are also 12-string versions. When an acoustic guitar is hooked up to an amplifier, it is referred to as acoustic/electric. Some acoustic/electric guitars incorporate a cutaway design, which makes it easier for electric guitar players to cross over to acoustic.
