MXR · pedal
The MXR M83 Bass Chorus Deluxe is an analog bucket-brigade chorus built specifically for bass, delivering lush, swirling modulation that preserves the dry signal at any setting. Bass and Treble controls shape the tone of the effect, a Flanger switch unlocks more dramatic sweeping modulation, and an X-Over switch rolls the modulation off below 100Hz so the lows stay tight and defined while shimmer is added to the highs. Variations in rate and width wrap notes in a clean, smooth sheen that many consider among the best bass chorus tones available. It suits bassists wanting subtle dimension or pronounced movement without losing low-end punch, and the flanger mode adds flexibility for more aggressive textures in rock, funk, and ambient bass.
