Amp pedals are designed to recreate the sound and behaviour of guitar amplifiers in pedal form. They can provide core tone shaping, gain structure, and EQ, and are often used as a direct replacement for an amp, as a pre-amp into a power amp, or as a tone-shaping foundation on a pedalboard. Amp pedals range from clean and edge-of-breakup sounds to high-gain styles, offering flexible amplifier tones in a compact format.
