6-Band Graphic Equalizer

The MXR M109S Six Band EQ is a 6-band graphic equalizer designed for guitar and bass applications. It covers all essential frequencies, with each slider capable of delivering +/-18dB of cut or boost for precise control over the sound. The pedal features noise-reduction circuitry, true bypass switching, and brighter LEDs for increased visibility. It is housed in a lightweight aluminum enclosure.
