What can cause a guitar string to break?

Guitar strings can break for a number of reasons, including: Age Strings can become oxidized or worn out over time, making them more likely to break. Rough surfaces Burrs or sharp edges on the saddle, nut, tuning machine, or frets can snag or wear down strings. Cleaning If you don't clean your strings after playing, debris and gunk can build up and cause the metal to oxidize, making it more likely to break. Metal fatigue Winding strings incorrectly around the tuning posts can cause kinks in the wire, which weakens the string and makes it more likely to break. Corrosion If you don't store your guitar in a climate-controlled environment, corrosion can destroy the strings. Alternate tunings Using the wrong string gauge for the tuning you're playing can also cause strings to break. Pick The thickness and sharpness of your pick can also affect how long your strings last. read less
