Blackbeard Green Cap Capacitors - 0.47UF 100V

Manufacturer	Blackbeard
Model Number	CAP-GC-47

Capacitors use metal plates and non-conducive substances (or dielectric) to divert the flow of electricity (frequencies), effectively converting low frequencies that flow into it, into higher frequencies flowing out of it. They are measured in Farads (F) and capacitors for guitars are in fractions of a Farad, thus calculated in uF.
A capacitor is usually soldered in between the pickup and jack as a shortcut to the grounding wire.
The capacitor and pot work together to produce the tone. The below is a table of the most commonly found matching of Capacitors to Control Pots:
