The pop-folk style being very broad, it is difficult to identify material specific to this style. Don’t worry, at first, you will just need to have a folk guitar, or an electric guitar depending on your preferences. However, avoid the use of a classical guitar, which is a little less suitable for playing this style of music.
Feel free to ask about the equipment of guitarists whose sound you like! It is a good way to gradually find your way around the mass of guitarist equipment you may see. It will also allow you to get the sound you are looking for, by adding an effect pedal on your electric guitar for example.
You got it, there is not typical equipment to play folk music on the guitar. Just prefer versatile guitars, and your playing will do the rest!
