HENGYEE Roller String Trees String Retainer Guides Compatible with Strat Tele Style Electric Guitar Parts Replacement Pack of 2pcs with Mounting Screws New Items. (Black)

These are a single coil design machine winding and calibrated with the magnetic field to produce double the output inductance of regular single coils with each set of pickups having its own unique flavour. This special winding also has the added advantage of keeping the Ohms roughly the same as a vintage wound single coil..
Each pickup is designed for a specific location to match up with the increasing width between strings and produces the ideal power for that tonal position..
The mid position pickup is reverse wound and opposed magentic polarity to ensure true hum cancelling properties in switch positions 2 and 4. All pickups are wax potted to reduce unwanted noise.
Flat pole pieces and no trapezoid bases mean these pickups are suitable for left and right handed guitars..
Supplied with screws and springs for fixing. All coils are wax potted.
