Welcome, you are looking at a great piece. This is the DiMarzio The Chopper Stratocaster Pickup in Black. Wiring: 4-Conductor. Magnet: ceramic. Output mV: 260. DC Resistance: 9.16k Ohm. The Chopper Strat pickup has more power centered in the mids and low end for a bigger sound with more crunch, and the side-by-side twin blade construction eliminates misaligned poles and string pull problems, as well as hum and noise. Tonally it is a cross between a single-coil and a full-size humbucker, with more power and fullness than a single but with more clarity and articulation than a full-size 'bucker. An excellent bridge pickup, or neck pickup to match a hotter bridge humbucker. We are an authorized DiMarzio dealer. Don't pass this by.
