More than anything the string gauge will determine the playing feel of your acoustic guitar strings and by extension, your guitar itself. Thicker gauge strings require more hand strength to play, however, they also enhance sustain and deliver a warmer, more bass-heavy sound.
Slap on a set of lighter gauge strings and you’ll find your hands flying across the guitar neck and bends in particular will be much easier. You’ll lose some sustain, but for a lot of players and particularly beginners, the playing benefits outweigh the tonal cost.
String gauge is a very personal choice, and thankfully acoustic guitar strings are relatively inexpensive items, so it’s always worth trying out a few different gauges to find the set that matches your particular playstyle.
