Ceramic Capacitors

The value of the capacitor will have an impact on the tone control and how much treble is cut off when the knob is turned. The brand and type of capacitor is less significant but many guitarists believe it influences the tone of the guitar.

Capacitor Values
In the early years 0.02 mf (or 0.022 mf) capacitors were commonly used on guitars with humbucker pickups and 0.05 mf (or 0.047 mf) were seen on guitars with single coil pickups.

In recent years this convention has changed and manufactures such as Seymour Duncan are recommending the use of 0.05 mf (or 0.047 mf) for humbuckers and 0.02 mf (or 0.022 mf) for single coils.
