Another 21+ Single Coil Acoustic Guitar. A single coil pickup is a type of magnetic transducer, or pickup, for the electric guitar and the electric bass. That being said, if i am playing metal i use one of my hb equipped guitars. I have a dimarzio chopper in one of my guitars and its good, but not the best.
