Zoom A1 Four Multi-Effects Processor

With specially engineered effects, built-in looper and drum machine, the A1 FOUR is the first
Multi-Effects Processor designed for a variety of acoustic string and wind instruments.

The A1 FOUR is preloaded with over 80 effects, including more than 35 new groundbreaking effects designed and engineered for acoustic instruments.

Popular effects such as Distortion, Chorus and Wah are typically designed to work with the electric guitar. The A1 FOUR provide all-new effects that are engineered to process the unique signals generated by acoustic instruments.

For example, with the sax and trumpet, original acoustic sounds are controlled by the musician blowing the horn with more or less intensity. As an example, the Wah effects are uniquely re-voiced in the A1 FOUR by adding a Low Pass Filter (LPF) to best control the processed frequency response of the instrument. This allows musicians to hit the peak frequency points while still blowing naturally into the instrument, without losing any expected sonic response of attack and release.

With a free download, ZOOM Guitar Lab software explore an endless world of patches and effects. And with its added ability to edit effects and arrange patches designed for Acoustic Instruments, you can experiment and create endless combinations.

The Zoom MAA-1 mic adapter provides a hassle-free connection to the A1.  It works with dynamic microphones and even provides phantom power for condenser mics. Add effects to any acoustic instrument and adjust gain settings with the MAA-1’s easy-access controls.
