A power amp is an electronic amplifier that amplifies low-power electronic audio signals (electric guitar pickups, pedal/preamp/amp modelers) to a level that is strong enough to drive loudspeakers. It is typically the final stage of an audio signal chain before going to the speaker cabinets. The output signal of preamp pedals and amp modelers are generally too weak to drive a cabinet, and this is where Loudster comes in.
