## What each position does

- Neck: Neck pickup (both coils). Source: Engine reading with the pickup selector stepped; mini-toggles share that position index.
- Neck + bridge: Neck pickup (both coils) and Bridge pickup (both coils) in parallel. Source: Engine reading with the pickup selector stepped; mini-toggles share that position index.
- Bridge: Bridge pickup (both coils). Source: Engine reading with the pickup selector stepped; mini-toggles share that position index.

- Mini-toggle lever states are not independently enumerated; they share the pickup-selector position index.
