This raw electrical signal is incredibly weak, typically ranging from , with a high output impedance. The primary job of a guitar amplifier is to take this fragile, high-impedance AC signal and boost it into a low-impedance signal powerful enough to physically move a heavy loudspeaker cone.

: For the best sound and safety of the equipment, the output of the amp must match the "load" (impedance) of the speaker cabinet. guitar amplifier electronics basic theory pdf

The preamp is also where much of the amp's character is shaped. The determines how much amplification occurs, directly affecting the amount of distortion. Early preamp stages often use simple common-cathode (tube) or common-emitter (transistor) configurations to provide high voltage gain. This raw electrical signal is incredibly weak, typically
