What Are Decoupling Capacitors?

October 2, 2024

While not as prominent in guitar pedals as coupling capacitors, decoupling capacitors are used in electronics and guitar pedals to help direct currents as needed. This is usually to smooth out DC electrical signals or prevent noise from AC signals. This may seem very similar to coupling capacitors, but there is a big difference. Coupling […]

What Are Coupling Capacitors?

September 13, 2024

In guitar pedals and electronics in general, coupling capacitors are important to keep different parts of a circuit separate and to prevent DC power and other noise from moving from one sub-circuit to another. All in all, it’s quite simple, and that’s really the explanation… but if you want to know more, read on for […]
