Description
The MXR Stereo Chorus M134 sits on your board as a tone-shaping chorus rather than a one-trick modulation box. It’s built to swing from a barely-there shimmer on clean arpeggios to a wide, watery swirl that fattens strummed rhythm parts and beefs up distorted power chords, all without adding noise or mud to your signal.
Dial in the character with Rate and Width, then use the Intensity knob to set how much of the effect blends into your dry signal. What sets this pedal apart is the dedicated Bass and Treble EQ, which shapes only the modulated frequencies, letting you sculpt the chorus tone independently from your core guitar sound. Run it in mono for a straightforward modulation stage, or take advantage of the stereo outputs to spread the effect across two amps for a genuinely huge, immersive spatial image.
For players who want the swirl without losing low-end punch, the Bass Filter button restricts the chorus effect to the high frequencies only, keeping your fundamental tone tight and your bottom end intact — a smart placement choice for anyone running this ahead of a clean or slightly dirty amp channel.
