... Typically, in a guitar amp, somewhere around 6-10dB of feedback is used. Most guitar amps have a "presence" control, which boosts the high frequencies. It accomplishes this not by actually boosting the highs in the forward path of the output circuit, rather by cutting the amount of high frequencies ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
