MXR M109S Six Band EQ Pedal | No Limit Guitar Co, Idaho Falls
The MXR M109S Six Band EQ Pedal is a compact, rugged, and genuinely versatile tool for guitarists and bassists who want precise frequency control at their feet — six EQ sliders with 18dB of cut or boost each covering the full tonal spectrum, low-noise circuitry that keeps your core tone intact, true hardwire bypass switching, and a rugged aluminum housing built to handle the demands of regular pedalboard use. Whether you're sculpting mid-scooped rhythm tones, cutting unnecessary low-end for a cleaner live sound, removing quack from an acoustic-electric plugged in, boosting specific frequencies for solos and leads, or fighting feedback in a difficult room, the M109S handles every application with the simplicity and directness of a graphic EQ's visual, hands-on slider layout.
Product Overview
Graphic EQ pedals are among the most practically useful tools on any pedalboard — and the MXR Six Band EQ earns its place as one of the most trusted and widely used graphic EQ stompboxes available. Its six frequency bands cover the tonal range relevant to guitar and bass in a layout that makes the overall EQ curve immediately readable at a glance — the slider positions create a visual representation of what the EQ is doing to the signal, which makes both setting up a specific tone and making quick adjustments during a performance intuitive and fast in ways that parametric EQ controls don't allow.
Each of the six sliders provides 18dB of cut or boost — a substantial range that accommodates both subtle, corrective EQ for fixing tonal problems in a specific room or amplifier, and dramatic tonal shaping for distinctly different sounds within a single performance. Used as a boost pedal for solos and leads, the M109S can target specific frequency ranges rather than boosting the full signal uniformly — a mid boost for a lead tone that cuts through a dense mix, a presence boost for added articulation, or a combination of boosts that creates a completely different character from the rhythm tone without touching the amplifier's controls.
The low-noise circuitry is the technical specification that makes the M109S genuinely useful in professional performance and recording contexts — EQ pedals that introduce noise into the signal chain at high boost settings negate the tonal benefits of the boost itself. MXR's low-noise design maintains signal integrity through the full 18dB boost range, ensuring that boosted frequencies add the intended tonal character rather than adding noise alongside it. MXR True Hardwire bypass switching ensures the pedal has zero effect on the signal when bypassed, and bright LED indicators on the sliders provide at-a-glance visual confirmation of the current EQ curve setting even in dim stage lighting.
The rugged aluminum housing keeps the M109S compact — at just 2.37" wide, 4.37" deep, and 0.77 lbs. — while providing the structural rigidity needed to handle regular stomping and pedalboard transport without the flex and mechanical wear that plastic enclosures develop over time.
Ideal For
- Guitarists and bassists who want precise, visual, hands-on frequency control for corrective EQ, feedback fighting, and tonal shaping from a single compact pedal
- Players who want a sculptable boost for solos and leads that targets specific frequencies rather than boosting the full signal uniformly
- Acoustic-electric players who need to remove quack, thin out harsh frequencies, or add warmth to a plugged-in acoustic tone
- Live performers who need to compensate for room acoustics, stage monitoring issues, and amplifier tonal imbalances without adjusting amp controls mid-set
- Guitarists and bassists in Idaho Falls looking for one of the most trusted and widely used graphic EQ stompboxes available at a compact, pedalboard-friendly size
Key Features
Six EQ Sliders with 18dB Cut/Boost Each
Six frequency bands with 18dB of cut or boost per slider cover the full tonal spectrum relevant to guitar and bass — enough range for both subtle corrective EQ and dramatic tonal shaping from a single pedal.
Sculptable Boost for Solos and Leads
With 18dB available on each slider, the M109S works as a boost pedal that targets specific frequencies — a mid boost for lead tones, a presence boost for articulation, or any custom boost curve that suits the musical context.
Low-Noise Circuitry
MXR's low-noise design maintains signal integrity through the full boost range, ensuring that frequency boosts add intended tonal character without introducing noise into the signal chain.
MXR True Hardwire Bypass
True hardwire bypass switching ensures zero effect on the signal when the pedal is bypassed — the M109S is completely transparent to the signal path when not engaged.
Bright LED Slider Indicators
LED indicators on each slider provide at-a-glance visual confirmation of the current EQ curve setting in any lighting condition — stage-ready readability.
Rugged Aluminum Housing
A compact aluminum enclosure provides the structural rigidity needed for regular stomping and pedalboard transport without the weight or bulk of larger EQ units.
