The A1X FOUR is the first Multi-Effects Processor designed for a variety of acoustic string and wind instruments. With a built-in looper and drum machine, the A1X FOUR is preloaded with over 80 effects, including more than 35 new groundbreaking effects designed and engineered for acoustic instruments.

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.

From the bright sound of electric jazz to our signature Auto Wah sound effect, the 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.

From the rich, full sound of a string symphony to the raw, distorted explosion of metal, the A1X FOUR have effects for every genre.
