Series / Parallel Pickup Switching
Position 1 - Bridge Humbucker
Bridge in Series - Full, thick and high-output humbucker tone
Bridge in Parallel - Cleaner, brighter and more open tone
Position 2 - Bridge + Neck
Both in Series - Full and powerful combined humbucker tone
Bridge Series + Neck Parallel
Bridge Parallel + Neck Series
Both in Parallel - Cleaner, more articulate combined tone
Position 3 - Neck Humbucker
Neck in Series - Warm, thick and full humbucker tone
Neck in Parallel - Cleaner, brighter and more articulate tone
The two push-pull pots provide independent control over each pickup:
Volume Push-Pull - Neck pickup Series / Parallel
Tone Push-Pull - Bridge pickup Series / Parallel
This gives a total of 8 possible pickup configurations, combining the traditional 3-way switching with independent Series / Parallel control for both humbuckers.
The push-pull pots allow the neck and bridge humbuckers to switch between series and parallel wiring.
The volume push-pull controls the neck pickup, while the tone push-pull controls the bridge pickup.
Series mode is the normal humbucker mode, delivering a fuller, thicker and higher-output tone with increased midrange and stronger sustain.
Parallel mode produces a cleaner, more open and articulate tone with reduced output and a character closer to a single-coil response. Unlike coil-splitting, parallel mode retains hum-cancelling operation, making it less susceptible to unwanted noise when gain is engaged.
This provides additional tonal versatility without changing the pickups themselves.
