Next up let's have a look at the materials the best acoustic guitar strings are made of. The most commonly occurring materials are 80/20 Bronze and Phosphor Bronze. The difference is slight, but it does change the tone and playing feel ever so slightly.
80/20 Bronze is the choice for the acoustic guitar player looking for a zingier, brighter tone. Their construction is 80% copper and 20% zinc (hence the name) and it’s this composition that highlights the highs in your guitar’s sound.
Somewhat confusingly, Phosphor Bronze strings also contain copper and zinc, however, they also have a very small amount of phosphorous too. The amount is very slight, but it adds up to a different-sounding acoustic guitar string. A set of Phosphor Bronze strings will be warmer in tone, leaning more towards the low end of the scale in their sound.
