# Two humbuckers, standard 5-way blade with coil split, one volume Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-five-way-blade-split-volume Two humbuckers · Standard 2-pole 5-way blade · Coil split · One 500k volume Seymour Duncan sheet: two humbuckers on a standard 5-way lever switch with a 500k volume. Positions 1-3 give bridge, both and neck humbuckers; positions 4 and 5 split through the switch's second pole and the bridge series link. Drawing: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-five-way-blade-split-volume.svg (back of controls) ## Parts and values - Neck Pickup: Seymour Duncan Neck Pickup; compatible example (Jazz Model SH-2 Neck) - Bridge Pickup: Seymour Duncan Bridge Pickup; compatible example (JB Model SH-4) - 5 Way Blade: 5 Way Blade; compatible example (Oak Grigsby 5-Way) - Volume 500k: Volume 500k; 500k; compatible example (CTS 500k Audio Pot) - Output Jack: Output Jack; compatible example (Switchcraft \#11) - Bridge Ground: Bridge Ground; generic (Bridge ground wire) ## Specific to this wiring - Title: 2 HUMBUCKER \| 1 VOLUME, 5 WAY BLADE (with coil split). - Sheet text: 'This mod uses a standard 5-way lever switch, intended to show a versatile alternative with 2 humbucker pickups. For more complex switching, a megaswitch or 4 position switch is needed.' - Printed legend: 'Position 1: Bridge Humbucker. Position 2: Neck Humbucker plus Bridge Humbucker. Position 3: Neck Humbucker. Position 4: Bridge Humbucker plus Neck Split. Position 5: Bridge Split.' - The legend disagrees with the drawing in position 4. This diagram follows the drawing: the bridge red & white are on the blade lug live in positions 4-5 and the bridge black on the lug live only in positions 1-2, so position 4 plays the bridge SPLIT (from its series link) plus the neck split, in parallel, not the full bridge humbucker the legend prints. - The blade lugs are not numbered on the sheet. They are read as a standard two-pole 5-way: the left row's common is its bottom lug (T4), then T2, T1 and T3 going up; the right row's common is its top lug (T8), diagonally opposite, then T7, T5 and T6 going down. Pole A: T3 live in positions 1-2, T1 in 2-4, T2 in 4-5; pole B: T7 in 1-2, T5 in 2-4, T6 in 4-5. Position 1 is the bridge end. - The right row's top lug (T8) and second lug (T7) are drawn empty. T8 is a floating common: in position 4 it joins T5 (grounded) to T6 (the neck red & white), which grounds the neck series link and leaves the neck black coil. - Both pickups' green and bare wires, the blade's grounding lug, the jack sleeve and the 'Bridge Ground' wire go to the volume's Solder spot; the volume's right lug is drawn bent back onto its casing under a second Solder spot. - Source legend: the grey 'Solder' spot = location for ground (earth) connections. - Tip (hot output). Sleeve (ground): the inner, circular portion of the jack. ## Connections 1. Neck green → Volume Solder spot (case, green) 2. Neck bare → Volume Solder spot (shield, bare): Drawn grey. 3. Bridge green → Volume Solder spot (case, green) 4. Bridge bare → Volume Solder spot (shield, bare): Drawn grey. 5. Blade right row, third lug → Volume Solder spot (case, black): Hops over the neck red and white, loops round the right side and back to the Solder spot. 6. Volume right lug → Volume casing (lower Solder spot) (case): Lug bent onto the casing. 7. Volume Solder spot → Jack sleeve (wire, black) 8. Bridge Ground → Volume Solder spot (wire, black) 9. Neck black → Blade left row, second lug (wire, black): Hops over the neck white and red. 10. Neck white → Blade right row, bottom lug (wire, white): Runs with the neck red over the top of the switch. 11. Neck red → Blade right row, bottom lug (wire, red): With the neck white. 12. Bridge black → Blade left row, top lug (wire, black): Hops over the neck green and bare. 13. Bridge white → Blade left row, third lug (wire, white): Labelled 'red & white' with the bridge red. 14. Bridge red → Blade left row, third lug (wire, red): With the bridge white. 15. Blade left row, bottom lug → Volume left lug (wire, black): Straight down, then back up to the lug under the pot. 16. Volume middle lug → Jack tip (wire, black) ## What each position does - Bridge humbucker: Bridge Pickup (both coils). Source: Position 1: Bridge Humbucker. - Neck humbucker + bridge humbucker: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. Source: Position 2: Neck Humbucker plus Bridge Humbucker. - Neck humbucker: Neck Pickup (both coils). Source: Position 3: Neck Humbucker. - Bridge split + neck split (legend: bridge humbucker + neck split): Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. Source: The printed legend says 'Position 4: Bridge Humbucker plus Neck Split', but the drawn wiring (followed here) gives the bridge humbucker split plus the neck split. The legend is wrong for this position; the drawing is a working circuit. - Bridge split: Bridge Pickup (split to one coil). Source: Position 5: Bridge Split. - The printed legend's position 4 ('Bridge Humbucker plus Neck Split') disagrees with the drawing; the expected states follow the drawing (bridge split + neck split). - Which coil of each humbucker remains when split follows the Seymour Duncan lead colours of the pickup; hum cancelling in position 4 is not claimed. - Pickup resistance is not specified, so no numeric meter readings are given. ## Check before plugging in - Positions 1, 2 and 3: bridge humbucker, both humbuckers in parallel, neck humbucker. - Position 4: expect roughly half the resistance of either split coil (two single coils in parallel), not a full humbucker in parallel with a coil. - Position 5: one bridge coil only. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_5WSPL\_1V, revision 2.
