Know before you buy
The 0.022uF value is the industry standard for humbucker-equipped guitars. It provides a balanced sweep when rolling off your tone knob, allowing you to darken the signal without it becoming muddy.
Yes, these are designed specifically for period-correct builds. They feature the classic bumblebee aesthetic and authentic Kraft Paper-in-Oil construction to match the look and sonic profile of vintage components.
Paper-in-Oil capacitors are prized for their smooth, musical high-frequency roll-off. Many players find they offer a more organic, vintage-voiced response compared to the clinical, sterile sound of standard ceramic or polyester film capacitors.
These capacitors measure 0.875 inches in length and 0.40 inches in diameter. While they fit most standard cavities, you should verify the available space in your specific guitar model, especially if you have a cramped control layout.
In a passive guitar circuit, the voltage passing through the tone pot is very low, so a 300V rating is more than sufficient. This rating ensures the capacitor is durable and reliable without being unnecessarily bulky.
