# Three stacked pickups, five-way, volume and two tones Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/three-stacks-five-way-volume-two-tones 3 stacks · 5-way · 1V · 2T Three stacked pickups, five-way, volume and two tones. Transcribed from the manufacturer wiring sheet. Drawing: https://guitarwiring.app/wiring-diagrams/seymour-duncan/three-stacks-five-way-volume-two-tones.svg (back of controls) ## Parts and values - Neck pickup: Neck pickup; generic (Humbucker (four-conductor, Seymour Duncan colours)) - Middle pickup: Middle pickup; generic (Humbucker (four-conductor, Seymour Duncan colours)) - Bridge pickup: Bridge pickup; generic (Humbucker (four-conductor, Seymour Duncan colours)) - 5-Way Blade Switch: 5-Way Blade Switch; compatible example (Oak Grigsby 5-Way) - Volume 250k: Volume 250k; 250k; compatible example (CTS 250k Audio Pot) - Tone 1 (neck): Tone 1 (neck); 250k; compatible example (CTS 250k Audio Pot) - Tone 2 (middle): Tone 2 (middle); 250k; compatible example (CTS 250k Audio Pot) - .047 cap: .047 cap; 47nF; compatible example (Orange Drop .047µF) - Output jack: Output jack; compatible example (Switchcraft \#11) - Bridge ground: Bridge ground; generic (Bridge ground wire) ## Specific to this wiring - Stacked / rail-style pickups use generic four-conductor humbucker stand-ins; hum-cancelling stack construction is not modelled beyond the transcribed lug map. - Two Strat tones share one .047 µF capacitor via a jumper between tone-2 wiper and tone-1 capacitor lug; passive tone analysis is topology-only (toneReachesSignal). ## Connections 1.

Source: Engine reading of the transcribed board; matches the source legend. - Bridge + middle: Middle pickup (both coils) and Bridge pickup (both coils) in parallel. Source: Engine reading of the transcribed board; matches the source legend. - Middle: Middle pickup (both coils). Source: Engine reading of the transcribed board; matches the source legend. - Middle + neck: Neck pickup (both coils) and Middle pickup (both coils) in parallel. Source: Engine reading of the transcribed board; matches the source legend. - Neck: Neck pickup (both coils). Source: Engine reading of the transcribed board; matches the source legend. - Stacked / rail-style pickups use generic four-conductor humbucker stand-ins; hum-cancelling stack construction is not modelled beyond the transcribed lug map. - Two Strat tones share one .047 µF capacitor via a jumper between tone-2 wiper and tone-1 capacitor lug; passive tone analysis is topology-only (toneReachesSignal). ## Check before plugging in ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 3STK\_5W\_1V\_2T, revision 1.
