DiMarzio (full name: DiMarzio Musical Instrument Pickups, Inc.) is an American-based electronic manufacturing company, famous for its guitar pickups. The company also produces miscellaneous guitar accessories, such as cables, straps and hardware. DiMarzio became known for its Super Distortion model, which was the first after market replacement guitar pickup available to the mass market. It is still one of the most popular models. The Super Distortion pickup produced a higher electrical output than the pickups normally fitted as standard to guitars at the time. It has around twice the impedance of a PAF type pickup, and a stronger ceramic magnet. This drove the input stage of guitar amplifiers with roughly twice as much voltage as a PAF pickup, so that an overdriven distorted sound was easier to obtain.
