Six Band Graphic Equalizer MX-109

The MXR Six Band Graphic Equalizer (M109) is a compact 6-band graphic EQ that provides ±18 dB of boost or cut across the 100 Hz to 3.2 kHz frequency range, making it a versatile tool for shaping tone, tightening low end, boosting mids for solos, or cutting harsh frequencies. Its six illuminated sliders allow quick, precise adjustments, while the glow-in-the-dark graphics improve visibility on dark stages. Popular with players ranging from Eddie Van Halen to Dimebag Darrell, the Six Band EQ has long been used to refine amp voicing, create scooped-metal tones, or simply help a guitar stand out in the mix. The pedal features hardwire bypass and a rugged, pedalboard-friendly design.
