A1 FOUR For Acoustic Guitar, Saxophone, Trumpet, Violin, Harmonica, Acoustic Bass, and More

With specially engineered effects, built-in looper, and drum machine, the A1/A1X FOUR is the first Multi-Effects Processor designed for a variety of acoustic string and wind instruments.

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.

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. IR (Impulse Response) technology is used to capture the sonic fingerprint of all guitar shapes and bodies available on the A1 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.

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.

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 acoustically 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.

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 like 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.

Drums & Percussion Included

Choose from 68 rhythm patterns designed for acoustic music including Samba, Reggae, and Jazz. Play along with a variety of time signatures.
