Such heavy sounds can usually only be produced through active pickups, the SH-8 masters this, however, in it's passive construction. The combination of three ceramic magnets, over-wound coils and twelve black oxide cap screws make the SH-8 Invader an electrifying force of energy. The wide range of magnetic field strength and pressure pumps to the amp and makes relentless heavy sounds without end. Ideal for punk, garage, thrash, metal and many other heavy rock styles.
