Passive humbucker pickup. In the past, if you wanted humbucker tone, P90 tone, and Strat tone, you would have needed three different guitars. But now, the P-Rails humbucker delivers all three sounds in a pickup that is a drop-in replacement for any stand sized humbucker slot. Using any 3-way (on-off-on) mini-switch, this unique hybrid humbucker can be split to give you an super fat P90, or it can be split to the Rail coil for Strat-like tone. With both coils on, you get a big sounding humbucker that packs a nice full punch. - Number of Conductors: 4 - DC resistance: 13 kOhm - Colour: Black.
