MXR M108S 10-Band Graphic EQ

The MXR M108S: Pro-Grade Tone Sculpting in a Polished Aluminum Chassis

Precision EQ Pedal for Guitar and Bass Players

The MXR M108S 10-Band Graphic EQ is built for players who demand maximum tonal control. Whether you're compensating for venue acoustics, carving out a unique sonic footprint, or pushing the front end of your amp, this pedal offers precision shaping in a rugged, road-ready format. The ten frequency bands span from deep subs at 31.25 Hz all the way up to shimmering highs at 16 kHz, with up to 12 dB of boost or cut per band, letting you tailor your tone with surgical accuracy.

Dual Outputs and Expanded Control Options

What sets the M108S apart from its predecessors is its flexible routing and expanded utility. With dual outputs, you can send your sculpted signal to two separate destinations—ideal for wet/dry rigs, stereo setups, or splitting between amp and interface. Independent sliders for volume and gain give you total control over your signal’s intensity and presence, allowing the pedal to function as a clean boost or pre-EQ driver when needed.

Low Noise, True Bypass, and Built to Last

The M108S is housed in a sleek aluminum chassis that’s lightweight yet ultra-durable. Upgraded noise-reduction circuitry keeps your signal chain clean, even in high-gain environments. And thanks to true hardwire bypass, your core tone stays pristine when the pedal is disengaged. Bright blue slider LEDs make it easy to see your EQ settings on a dark stage, and a single footswitch keeps operation simple and reliable.

Perfect for Live and Studio Applications

From taming boomy bass frequencies to pushing upper mids for solo clarity, this pedal handles everything from subtle shaping to aggressive tone manipulation. Whether you're a bassist smoothing out room resonance or a guitarist cutting through a mix, the M108S adapts easily to your needs. It shines on pedalboards of all sizes and is equally at home in a live rig or studio rack.

Powered with 18 Volts for Superior Headroom

Unlike standard 9V pedals, the M108S runs at 18 volts, delivering enhanced headroom and dynamic clarity. While the required power supply is not included, it is compatible with industry-standard 18V DC units such as the Dunlop ECB004, DC Brick, or Iso-Brick. This makes it easy to integrate into professional-grade pedalboards with existing power solutions.
