Two humbuckers · Five-way blade (with coil split) · 500k volume · Two 500k tones

Neck and bridge Seymour Duncan humbuckers on a standard two-pole 5-way blade, one 500k volume and a 500k tone for each pickup (.047 caps), wired on each pickup's black lead before the blade. As drawn: bridge, both humbuckers, neck, bridge split + neck split, bridge split. The printed legend calls position 4 'Bridge Humbucker plus Neck Split', which the drawing does not do.

## Specific to this wiring

- 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.'
- LEGEND DISAGREES WITH THE DRAWING IN POSITION 4. This diagram follows the drawing, which is a working circuit: position 4 gives the bridge humbucker SPLIT plus the neck humbucker split, in parallel, not the full bridge humbucker the legend prints. For the legend's position 4 the bridge black would have to be live in positions 1, 2 and 4, but it is drawn on the blade lug that is live only in positions 1-2. Seymour Duncan's 2015 upload of this sheet (archived 2017-06-22) shows the same wiring with no legend; a Seymour Duncan forum post (GuitarDoc, 2019) about the one-tone sister sheet, 2H\_5WSPL\_1V\_1T, whose switch wiring is the same, describes it as '4. Bridge (screw coil) + Neck (slug coil)', which agrees with this reading. Positions 1, 2, 3 and 5 match the legend.
- 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.'
- The blade lugs are not numbered on the sheet. They are read as a standard two-pole 5-way: the upper (left) row's common is its bottom lug (T4), then T2, T1 and T3 going up; the lower (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 lower row's top lug (T8) and second lug (T7) are drawn empty. T8 is a floating common: in positions 4-5 it joins T5 (grounded) to T6 (the neck red and white), which grounds the neck series link and leaves the neck black coil.
- The bridge red and white (T2) reach the output in positions 4 and 5 while the bridge black is disconnected, so the bridge's red-to-green coil is what plays: the bridge split takes its output from the series link.
- Each pickup's black goes first to its own tone's left lug, and from there on to the blade: bridge tone to the upper row's top lug, neck tone to the upper row's second lug. Each tone's middle lug feeds its .047 cap to its Solder spot; the right lugs are drawn unused.
- Unmarked crossing: the neck black's run to the neck tone crosses the vertical blade-common-to-volume wire beside the 'Volume 500k' label with no hop and no dot. Every other crossing on this sheet is drawn with a hop, and the sheet marks joints with dots at lugs and Solder spots. It is read as NOT joined: a joint there would put the neck pickup on the output in every position, which contradicts every line of the legend (including positions 1 and 5, where the drawing and the legend agree on bridge-only sounds) and differs from the one-tone version of this sheet, where the neck black runs straight to the blade.
- Both pickups' green and bare wires and the blade's grounding lug go to the volume Solder spot. The volume Solder spot is wired to the bridge tone Solder spot, which also takes the neck tone Solder spot, the jack sleeve and the 'Bridge Ground' wire.
- The volume's right lug is drawn bent back onto its casing under a second Solder spot.
- The label 'black' printed beside the bridge pickup's cable has no wire next to it on this sheet; the bridge black is the lead that runs along the bottom to the bridge tone.
- Source legend: the grey 'Solder' spot = location for ground (earth) connections.
- Tip (hot output). Sleeve (ground): the inner, circular portion of the jack.

## 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 says 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 generic pickup model; 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: expect roughly one coil of the bridge humbucker.
- Each tone should act only on its own pickup: the bridge tone in positions 1, 2, 4 and 5 through the bridge pickup, the neck tone in positions 2, 3 and 4.
