How often do you change your strings?
Guitar strings age in several ways - they stretch, tarnish and get contaminated with sweat and dirt. Professional players change strings before each gig. For general light home use we would recommend you change your strings every 6 months as a minimum. If you play a lot then every few weeks would be more appropriate.
Changing strings can seem like a chore, but the more you do it, the easier it gets... and you will always be rewarded with a brighter, fresher cleaner sound from your guitar - whether it is electric, acoustic or classical.
TOP TIP!: Buy a guitar string winder (aka Peg winder) to help change your strings. Even the cheapest winder will make the job easier, but you can also get one with a built in string cutter for a neat job with no fuss. You can even get an electric powered peg winder to make the job super-easy!
