Carl Martin Chorus XII

Carl Martin · pedal

The Carl Martin Chorus XII is an analog chorus pedal using twelve stages of bucket-brigade device (BBD) delay to create rich, warm chorus modulation. The 12-stage BBD architecture produces a fuller, more complex chorus sound compared to standard four or eight-stage designs, with deeper pitch modulation and a more immersive spatial character. Boutique Danish analog construction. Controls include Rate and Depth for speed and intensity of the chorus effect. Suited for players seeking premium analog chorus with maximum harmonic richness.
