# Two humbuckers, three-way blade, two push/pull series/parallel volumes

Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-blade-two-push-pull-series-parallel-volumes

Two humbuckers · Three-way blade · Two push/pull volumes (series/parallel each)

Neck and bridge Seymour Duncan humbuckers, each with a 500k push/pull volume that switches that pickup between series and parallel coils, before a three-way blade. No tone control.

## Parts and values

- Neck Pickup: Neck Pickup; generic (Humbucker (four-conductor, Seymour Duncan colours))
- Bridge Pickup: Bridge Pickup; generic (Humbucker (four-conductor, Seymour Duncan colours))
- 3-Way Blade Switch: 3-way blade; compatible example (CRL 3-Way Blade)
- Neck Volume 500k push/pull series/parallel: Neck Volume 500k push/pull; 500k; compatible example (500k Push-Pull DPDT)
- Bridge Volume 500k push/pull series/parallel: Bridge Volume 500k push/pull; 500k; compatible example (500k Push-Pull DPDT)
- Output Jack: Output Jack; compatible example (Switchcraft \#11)
- Bridge ground: Bridge ground wire; generic (Bridge ground wire)

## Specific to this wiring

- Each volume push/pull uses the Seymour Duncan series/parallel DPDT pattern: white and red go to the middle row, green/bare and black to the row nearest the pot, with a jumper from the left middle lug to the right top lug.
- Down is series; pulled is parallel for that pickup.
- Blade tags are unlabelled in the source; mapped by function to the catalog CRL 3-way blade.
- Solder = location for ground (earth) connections.

## What each position does

- Neck; neck PP down; bridge PP down: Neck Pickup (both coils). Source: Pulling a volume puts that pickup's coils in parallel; down is series.
- Neck; neck PP down; bridge PP up: Neck Pickup (both coils) and Bridge Pickup (both coils). Source: Pulling a volume puts that pickup's coils in parallel; down is series.
- Neck; neck PP up; bridge PP down: Neck Pickup (coils in parallel). Source: Pulling a volume puts that pickup's coils in parallel; down is series.
- Neck; neck PP up; bridge PP up: Neck Pickup (coils in parallel) and Bridge Pickup (both coils). Source: Pulling a volume puts that pickup's coils in parallel; down is series.
- Neck+Bridge; neck PP down; bridge PP down: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. Source: Pulling a volume puts that pickup's coils in parallel; down is series.
- Neck+Bridge; neck PP down; bridge PP up: Neck Pickup (both coils) and Bridge Pickup (coils in parallel) in parallel. Source: Pulling a volume puts that pickup's coils in parallel; down is series.
- Neck+Bridge; neck PP up; bridge PP down: Neck Pickup (coils in parallel) and Bridge Pickup (both coils) in parallel. Source: Pulling a volume puts that pickup's coils in parallel; down is series.
