    Extraordinary Effects

    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.

    Acoustic Guitar Modeling
    Add depth and dimension with acoustic emulators and modeling. Refresh your instrument's natural sound, allowing your live performances to sound just like your studio recordings. Select and hone in on the tone of your favorite guitar make and style.

    The A1/A1X FOUR make it easier than ever to process the sound of your own Acoustic Guitar. With a selection of 15 factory presets (plus13 more available as free download on Guitar Lab), you can select your favorite AG MODEL, D-28 for example, and recover instantly the sound character of that renowned and original body shape.

    IR (Impulse Response) technology is used to capture the sonic fingerprint all guitar shapes and bodies available on the A1/A1X FOUR and via Guitar Lab. Each AG MODEL can be adjusted with 4 parameters (Gain, Bass, Mid, Treble) to control the volume and refine the audio output of your modeled sound.

    In Patches you can also set the AG Pickup Selector (AG PU SEL) to match your guitar's pickup type (Piezo or Magnetic) and add a specific EQ modeled on a variety of dedicated processors.

    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.

    Take Your Trumpet Back To The Future
    From the bright sound of electric jazz to our signature Auto Wah sound effect, the A1/A1X gives you inspiration for any style you play. With the "Tp MD70" preset patch the Pedal Wah sound is tuned, resonates and adapts to the low frequency range and curve of the Trumpet.

    Turn Your Violine 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.

    More Body For Your Harmonica's Soul
    Play punchy, mid-range sounds of a blues harp, or experiment with your own new sounds. Breathing new life into your harmonica has never been so much fun.

    Play through the preset patch "Hm StevieW" and get that famous harmonica sound as the chorus's wet signal effect is modified to fit the frequency response of the chromatic harmonica.

    The A1/A1X even provides you with a truly effective simulation of the Bullet Mic, also known by harmonica players as the Green Bullet. Select the preset patch "Hm Juke" and now hear the legendary amplified, warm tone of the Green Bullet come to life, even when using any standard vocal microphone.

    Take Your Upright Bass To New Heights
    With focused highs and rich lows, the A1/A1X Four gives you control and flexibility from classical to rockabilly and all styles in between. Add octaves, select your piezo effect or create your own unique signature sound.

    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.

    The Perfect Partner
    The Zoom MAA-1 mic adapter provides a hassle-free connection to the A1/A1X FOUR. 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.

    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.
