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.

The Technology

Popular effects such as Distortion, Chorus and Wah are typically designed to work with the electric guitar. The A1X 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 A1X 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.
