Zoom A3 Pre-Amp & Effects for Acoustic Guitar


Reproducing the delicate tone of an acoustic guitar onstage can be challenging. Pickups have a tendency to make the sound flat and lifeless, while microphones often introduce feedback. Zoom's A3 provides the perfect solution. This compact pre-amp/effects pedal provides everything you need to restore and enhance the natural tone of your instrument, or even transform it into a different-sounding one altogether. Powerful remodeling features combined with great-sounding effects and advanced features such as feedback suppression, auto-chromatic tuner, 3-band equalization and a Clean Boost foot switch make the A3 the complete sonic toolbox for acoustic guitar.
