## Specific to this wiring

- Dave Mustaine active humbuckers drawn on the source sheet; catalog part seymour-duncan-blackout-humbucker is used as an active topology stand-in.
- Pickup whites land on the volume wipers with the outer lugs feeding the toggle as drawn.

## What each position does

- Always on (active): No pickup reaches the output. Source: Passive simulation is not applied to active pickups; wiring topology only.

- Active pickup gain and frequency response are not simulated.
- The catalog active buffer is approximated with seymour-duncan-blackout-humbucker terminals.
- Passive engine rules not verified (selectionReachesTip, volumeMutes); wiring topology matches the manufacturer diagram.
