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 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 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 Violin Into an Orchestra

From the rich, full sound of a string symphony to the raw, distorted explosion of metal, the A1 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” wet signal effect is modified to fit the frequency response of the chromatic harmonica. The A1 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 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.

The Technology

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.

Another example is the violin. The bowing attack is key to the expression of the violinist. To recreate the electrified sensation of distortion without losing the bowing attack, the DIST effect for Violin shifts the clipping 1 octave higher, boosts the high frequency and reduces the lows. This creates a more balanced saturation that suits the sonic characteristics of the violin.
