HUMBUCKER WIRING DIAGRAMS

LAMBERTONES HUMBUCKER COLOR CODE

"the Crema" or "the Grinder" Humbucker 3-way w/1 Vol & 1 Tone

Store image

Switch Positions:
Position 1 - Bridge
Position 2 - Bridge/Neck
Position 3 - Neck

This wiring schematic features a traditional 3-way blade OR toggle switch design. This diagram features vintage 2-wire conductor wire where the outside braided sleeve is the ground (-) and the inside black "push-back" wire is the hot (+).

NOTE:
This diagram will work with 2-wire or 4-wire humbuckers. If you're adapting 4-wire humbuckers solder the series link together (red/white wires) and tape off or cover with heat shrink. Then solder the green (+) to the switch and the black/bare to ground (-). (Wire colors dependent on the manufacturer, and we used Lambertones color coding for the example)

"the Crema" or "the Grinder" Humbucker 3-way Switch Push/Pull

Store image

Switch Positions:
Position 1 - Bridge
Position 2 - Bridge/Neck
Position 3 - Neck
Push/Pull (engaged):
Position 1 - Bridge SLUG side only (North polarity to slug side)
Position 2 - Bridge SLUG/Neck SCREW (maintains phase and hum-cancelling)
Position 3 - Neck SCREW side only (South polarity to screw side)

This wiring schematic allows traditional humbucker tones in all 3 positions. When the push/pull is engaged of the CTS tone pot you will split to Neck SCREW side or Bridge SLUG side depending on where your 3-way switch it positioned. Every position maintains phase.

NOTE:
This diagram will ONLY work with 4-wire conductor humbuckers where the magnetic polarity is the same, like we do here at Lambertones. For example, using this will NOT work with a set of PRS humbuckers.

"the Crema" Jazzmaster w/Rhythm Circuit

"the Blondie" + "the Crema" 3-way Switch, 1 Vol, 1 Tone, 470k w/Resistor

Store image

Switch Positions:
Position 1 - Bridge seeing 250k (South polarity)
Position 2 - Bridge/Neck seeing 150k
Position 3 - Neck seeing 500k (South polarity to screw side)

This wiring schematic enables your single coil bridge pickup to see its desired potentiometer value of 250k while allowing your neck humbucker to see its desired pot value at 500k. The compromise is a darker middle position that, depending on the resistor used, will be approximately 150k resulting in a darker than normal middle position. This compromise is good for those that use their single coil bridge pickup

NOTE:
This diagram will work with 2-wire or 4-wire conductor. To utilize a push/pull pot for a coil-split middle position, purchase the 4-wire conductor humbucker and solder the red & white leads to "C1" on the CTS Push/Pull tone pot and solder a ground wire to the "1" position. This will improve the "dark" character of the middle position.

"the Triple Shot"  HSS w/"the Crema/Grinder" 5-way Switch, 1 Vol, 1 Tone, 1 500k Push/Pull Tone

Store image

Switch Positions:
Position 1 - Bridge humbucker (when Push/Pull engaged splits to North polarity SLUG side)
Position 2 - Bridge/Middle (Push/Pull engaged splits to SLUG side and maintains phase and hum-cancelling)
Position 3 - Middle
Position 4 - Middle/Neck (hum-cancelling)
Position 5 - Neck

This wiring schematic utilizes a 4-wire humbucker in the bridge position and a 500k CTS push/pull pot. You can substitute with an Alpha style pot by soldering the red/white to the C1 position. The push/pull allows you to split the humbucker in either position 1 or 2. In position 2, the humbucker splits to the North polarity CW SLUG side to maintain phase and polarity with the South polarity CCW middle pickup. The push/pull tone pot rolloff only affects the bridge positions, and the 1st tone affects the neck and middle positions.

NOTE:
CW - Clockwise
CCW - Counter Clockwise
This diagram works with a 3 or 4-wire humbucker only. Replacing the push/pull pot with a standard 500k potentiometer will work with either a 2, 3, or 4-wire humbucker.
