About the Zoom A3 Pre-Amp

Pickup systems are the most popular option for amplifying acoustic guitars on stage, however most are unable to capture the unique tone of each instrument. As a result, different guitars can take on similar flat, electric-acoustic characteristics and they all sound the same when amplified or plugged into a PA.

Zoom's A3 is the first pedal of its kind. It allows players to restore the natural tone of their acoustic guitars while continuing to use pickup systems for amplification. In addition to being a powerful acoustic preamp, the A3 offers unrivaled acoustic remodeling features, amazing acoustic effects and much more for crafting acoustic guitar sounds for both live and studio applications.
