The A1X FOUR brings over 90 specialised effects to acoustic musicians, featuring more than 35 groundbreaking new effects specifically engineered for acoustic instruments. Guitar players can explore a multitude of warm, rich tones ranging from live "unplugged" performance sounds to the finger-picking styles of country and blues. The gorgeous effects and acoustic guitar modelling will take your instrument to places it's never been before.
Saxophone players will find the A1X FOUR makes it effortless to perform that gritty rock-and-roll sax growl, or use the lush custom-chorus effect to emulate jazz fusion sounds. The all-new "SaxChorus" effect creates a more natural double-track and thick tone response by softening the modulated sensation typical of chorus effects designed for electric guitar. Ready-made settings for EQ and compressors ensure your sax preserves its acoustically warm sound even when amplified through microphones.
Trumpet players can shift from bright electric jazz sounds to Zoom's signature Auto Wah effect, with the "Tp MD70" preset patch tuning the Pedal Wah sound to resonate and adapt to the trumpet's low frequency range and curve. Violin players can create rich, full string symphony sounds or dive into raw, distorted metal explosions. Harmonica players can achieve punchy, mid-range blues harp sounds or experiment with new tones, including the famous "Hm StevieW" preset and the legendary Green Bullet simulation through the "Hm Juke" patch.
Even upright bass players are catered for with focused highs and rich lows, providing control and flexibility from classical to rockabilly and all styles in between. Add octaves, select piezo effects or create your own unique signature sound - the A1X FOUR is the ideal effects unit for acoustic instruments.
