If you ever wanted to know what was inside a complicated electric guitar, this one has three pick ups, three control knobs, a push-pull switch, and a five way switch.

Each of those pick ups has a big ceramic bar magnet on the bottom of it. There’s only one electronic semiconductor: that small green capacitor, which reduces the tone.
The five-way switch allows you to select any pickup, or either adjacent pair in parallel.
The push-pull kicks in the bridge pickup in parallel with whatever else is selected.
But it’s already in with position 3 or 4.
So, you can add it to the neck pickup, or both neck and mid pickup.
That runs all three in parallel (and with tone bleed.) Something regular Strats don’t do.
So now you can quit laying awake at night wondering how these things work.
