Gain is the ratio between the magnitude of output and input signals. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls, that allow you to adjust the incoming signal to the amplifier.
What is a Buffer? Technically a buffer is a unity gain (0dB) amplifier circuit with a high input impedance and low output impedance. In practice buffer pedals are used to prevent high frequency âroll-offâ and preserve the brightness of a guitar when connecting it to long cables or effects pedals with lower impedance input stages.
