Dunlop MXR M108S Ten Band EQ Guitar Effect

Dunlop MXR M108S Ten Band EQ — Graphic EQ Pedal for Guitar and Bass

This model is a graphic equalizer pedal for guitar and bass that delivers precise tone control. With ten frequency bands spanning the audible spectrum, players can cut problem frequencies, boost presence, and reshape their rig in seconds. The M108S suits musicians who need an adaptable EQ for tone sculpting, feedback control, and signal splitting on stage.

Upgraded Circuitry and Dual Outputs

Compared to its predecessor, this version adds dedicated noise-reduction circuitry that keeps the signal clean at extreme boost settings. A second parallel output splits the signal to two amplifiers. Brighter LEDs on every slider improve visibility on dark stages.

Ten Carefully Tuned Frequency Bands

The ten bands cover 31 Hz to 16 kHz — nearly the full spectrum of human hearing. Each slider offers ±12 dB of boost or cut.

• Frequency bands include 31 Hz / 62 Hz / 125 Hz / 250 Hz / 500 Hz / 1 kHz / 2 kHz / 4 kHz / 8 kHz / 16 kHz, covering nearly the entire audible spectrum.
• Boost/Cut Range: ±12 dB per band — enough headroom for aggressive tone shaping

True Bypass and 18V Headroom

True bypass switching keeps the signal path unaffected when disengaged. The 18V operation — via the included Dunlop ECB004 adapter — provides extra headroom.

• Bypass Mode: True bypass (hardwire) — zero signal alteration when off
• Operating Voltage: 18 V DC — extra headroom for clean boost operation
• Current Draw: 48 mA — compatible with DC Brick, Iso-Brick, and Mini Iso-Brick power supplies

Inputs, Outputs, and Physical Construction

A 6.3 mm mono jack input feeds the pedal, while two 6.3 mm mono jack outputs send the EQ'd signal to two amps. The aluminum enclosure measures 124 × 92 × 54 mm and weighs 700 g.

• Input: 1 × 6.3 mm mono jack — standard instrument-level input
• Outputs: 2 × 6.3 mm mono jack — parallel outputs for signal splitting
• Dimensions: 124 × 92 × 54 mm / Weight: 700 g — compact aluminum housing
