## 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.
