Acoustic guitar pedals are built to enhance the natural voice of an electro-acoustic instrument rather than overpower it. Popular choices include preamps, EQ pedals, compressors, reverbs, chorus effects and feedback suppressors, all of which can help an acoustic guitar sound clearer, warmer and more balanced when amplified.
They are particularly useful for live players who plug directly into a PA, audio interface or acoustic amplifier. A well-chosen acoustic pedal can add body, control harshness, reduce feedback and give your performance a more finished sound while keeping the character of the guitar intact.
