Sustain

The MXR M-163 is a vintage rackmount Stereo Octave Equalizer, produced in the late 1970s and early 1980s. It features 10 bands of graphic EQ per channel, allowing precise tonal shaping for both guitar and bass in stereo or dual-mono setups. Known for its robust build and low-noise circuitry, the M-163 is prized for studio and live applications, offering detailed frequency control and classic analog warmth.
