Especially, the variable range of the MIDDLE band is wide, allowing you to freely create the "midrange character" of the sound. ⚫︎Operation Knobs and Usage Tips • LEVEL: Pedal output volume (balance adjustment with bypass) • DIST: Amount of distortion (gain amount) • LOW: Adjusts the low frequencies (bass range) • HIGH: Adjusts the high frequencies (high end) • MIDDLE: Midrange (frequency boost/cut amount) • MID FREQ: Selects the center frequency of the midrange (changes the "position" of the midrange) ◆Recommended for whom/what purposes? • For hard rock/metal bands who want to give their guitar sound both "sharpness and weight." • Guitarists who want a strong, cutting midrange for solo leads.
