It is the ideal tool for musicians who want to refresh the natural sound of their instrument and make live performances sound like studio recordings.

Professional Sounds for Acoustic Instruments

Zoom A1 FOUR opens up an endless world of sounds and effects dedicated to acoustic instruments. Through acoustic modeling and emulators, the device allows you to refresh the natural sound of your instrument, making live performances sound like studio recordings. You can select the sound of your favorite guitar model — for example, a D-28 — and within moments reproduce the tonal characteristics of that original body. The A1 FOUR multi-effects pedal makes acoustic guitar processing easier than ever. With 15 factory presets (and 13 additional ones available for free download via Guitar Lab software), you have instant access to ready-made, professional sounds.

The built-in looper allows recording up to 30 seconds of material in CD quality with seamless looping, enabling you to build multi-layered arrangements on stage or in the studio. The drum machine, featuring 68 rhythms tailored for acoustic music, complements the looper’s capabilities, creating a comprehensive tool for improvisation and composition. You can record playing parts, apply effects to them, and build full arrangements in real time — all within one compact device.

In MEMORY mode, you can easily jump between programmed sounds, making it simple to set up a complete setlist for a concert. In STOMP mode, you turn individual effects on and off with your foot — an ideal solution for live performances where quick reaction is needed. The two operating modes ensure full flexibility and adaptability to your playing style.

With Zoom Guitar Lab software, available for free download, you gain access to additional settings and the ability to edit effects and arrange sounds for acoustic instruments. You can experiment freely and create endless sound combinations. The Zoom MAA-1 adapter allows seamless connection of a microphone to the multi-effects pedal, working with both dynamic and condenser microphones (with Phantom power). Apply effects to any acoustic instrument and adjust sensitivity using the easily accessible knob on the adapter.

Enrich your guitar's tone with a wide range of warm and rich tonalities. From live unplugged performances to fingerstyle country and blues playing — there is plenty to choose from. Excellent effects and acoustic modeling enhance your instrument's sound, whether you are playing guitar, saxophone, trumpet, violin, or harmonica.
