Control cavity
The hollow route inside a body that houses the potentiometers, switches, wiring and often the output jack.
Its size and shape decide how easy the guitar is to wire and repair, and how much can be fitted later: a cramped, small cavity makes adding a push-pull pot or an active circuit awkward or impossible, while a generous one allows modifications. The cavity also affects the instrument's mass and stiffness slightly, and the backplate or the cover over it must be shielded if noise is an issue. On acoustics and hollowbodies, access is usually through a soundhole or the pickup opening instead.
Example: a guitar with a shallow control cavity may not accept a push-pull pot, which is why some split-coil mods are done with a mini toggle in a new hole instead.
