UNLOCK THE POTENTIAL OF YOUR ACOUSTIC GUITAR
Add a multitude of warm and rich tones to your guitar. From live "unplugged" performance sounds to the finger-playing style of country and blues, there's so much to choose from. Gorgeous effects and acoustic guitar modeling will take your instrument to places it's never been before.

GIVE YOUR SAX AN ENTIRELY NEW SOUNDSCAPE
Perform that gritty, rock-and-roll sax growl. Or use the lush custom-chorus effect to emulate the sound of jazz fusion. The A1/A1X Four gives sax players a soundscape of possibilities. The all-new "SaxChorus" effect delivers a more natural double-track and thick tone response by softening the modulated sensation typical of a chorus designed for the electric guitar. With ready-made settings for EQ and Compressors your sax will preserve its acousticly warm sound, even when amplified through mics.

TURN YOUR VIOLIN INTO AN ORCHESTRA
From the rich, full sound of a string symphony to the raw, distorted explosion of metal, the A1/A1X FOUR have effects for every genre.

GUITAR LAB SUPPORTED
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.

TAP INTO YOUR PERFORMANCE
Effortlessly toggle between patches and effects with two performance modes. MEMORY mode makes it easy to program your entire setlist by jumping from patch-to-patch. Use STOMP mode to turn individual effects on and off with the tap of your foot.

DRUMS & PERCUSSION INCLUDED
