Duke of Tone Overdrive

Designed in conjunction with indie pedal builder Analog Man, the MXR Duke of Tone Overdrive is for players who want to add a touch of warmth and grit to their rig while allowing the natural tone and feel of their high-end gear to shine.

External Controls

  • Footswitch toggles effect on/off (white LED indicates on)
  • OD/BOOST/DIST switch sets clipping mode
  • VOLUME knob adjusts overall output level
  • DRIVE knob adjusts overdrive intensity
  • TONE knob adjusts overall EQ

Basic Operation Power

  • The MXR® Duke of Tone™ Overdrive is powered
    by the Dunlop ECB003 9-volt adapter or an MXR®
    Brick™ Series power supply. This pedal cannot be
    powered by a battery.


  • Run an instrument cable from your instrument to the CSP039’s INSTRUMENT jack and another instrument cable from the CSP039’s AMPLIFIER jack into your amplifier’s input.
  • Start with knobs set to 12 o’clock.
  • Turn effect on by depressing the footswitch.
  • Use OD/BOOST/DIST switch to select your preferred clipping style:
  • OD mode engages soft clipping for a touch of grit and compression. Boost mode bumps up your signal loudly
    and clearly with no clipping. Distortion mode engages hard clipping for a grittier, more compressed sound and a
    bump in output level.
  • Rotate VOLUME knob clockwise to increase overall volume or counterclockwise to decrease it.
  • Rotate DRIVE knob clockwise to increase overdrive intensity or counterclockwise to decrease it.
  • Rotate TONE knob clockwise for a brighter sound or counterclockwise for a warmer sound.
