All you need to know about capacitors in guitar pedals
Usually, when building guitar pedals, we use all sorts of values. However, a voltage rating of 25V is usually more than enough because voltage in guitar pedals is most of the times limited to 9V or 18V.If you use a bigger value, no problem! Just pay attention to the size of capacitors (more about that later).

Capacitor Characteristics
When the leakage is very low such as in film or foil type capacitors it is generally referred to as "insulation resistance" ( R p ) and can be expressed as a high value resistance in parallel with the capacitor as shown. When the leakage current is high as in electrolytic''s it is referred to as a "leakage current" as electrons flow directly through the electrolyte.

capacitor
To achieve this you need multiple LC circuits covering different parts of that frequency spectrum. This is why you need a range of different capacitor sizes. In order to achieve your desired ESR, you may also need several capacitors in parallel rather than one, as the ESR goes in parallel as well and will therefore be lower.
The Difference Between MOM, MIM, and MOS Capacitors
Metal-insulator-metal (MIM) capacitors are another class of compact capacitors with distinct advantages. They are like a parallel plate capacitor, in which metal plates (electrodes) are separated by an insulating material (dielectric). These capacitors are widely used because they exhibit high capacitance per unit area.

Capacitor bank protection design consideration white paper
Capacitor banks are composed of many individual capacitor units electrically connected to function as a complete system. Units are connected in series to meet required operating voltage, and in parallel to achieve the required kvar (graphically represented in Figure 7). Capacitor banks require a means of unbalance protection to avoid
RC Circuit Basics
The input signal applies directly to the capacitor with a resistor in parallel with the output, as shown above. By arranging components in this way, high-frequency signals can pass, while the capacitor blocks any frequencies that are too low. Therefore, the capacitor acts as an open circuit if the oscillations stay above a minimum speed.
