DC Resistance (approx.): Neck humbucker: 7.5K (split coil 3.75K) Center single-coil pickup: 7.5K (split coil 3.75K) Bridge humbucker: 15K (split coil 7.5K) Hole spacing: Neck (N): 50mm Center (M): 50mm Bridge (B): 52mm Humbucking four wires: Black wire: Hot wire Green wire: Ground wire Red and white wires: for splitting coils Material: PVC guard and copper coil pickups Weight: 700 grams per set Compatibility: Fits most Fender Strat guitars Accessories Included: 1 x 3-ply guitar guard 3 Alnico 5 humbucking pickups 1 x 5-way switch 1 booster switch 3 potentiometers (1 volume, 2 tone, brass shaft) 4 single pole toggle switches 1 x 400V/200V Capacitor 1 Output Jack 11 screws Extra features: Two single-pole toggle switches bring new functionality: When the multiplex switch (first switch) is on, the neck pickup is active regardless of the 5-way switch setting. For example, switch on + 5-way switch in bridge position = neck and bridge pickups work together. The bridge pickup has a single-knife (push-pull) switch (second switch). With the single cutter switch on you will get a different tone, the humbucker will change to a single coil pickup tone, this will be very powerful.
