  • “Choose Maxon for distortion.” People often said that for the legendary overdrive OD880
    swept the music scene in 1977 - 1980’s.
    OSD9 is an updated version of original Maxon OD880 Overdrive/Soft Distortion.

  • OSD9 has two controls like OD880. Creates natural, soft and warm distortion like the sound of
    a tube amplifier.

  • Original UA741 op-amp installed for overdrive circuit offers low-noise overdrive sound.
    OSD9 has a passive type distortion circuit which differs from OD808/OD9.

  • True Bypass Switching with 4PDT mechanical switch. No tone changes when switching bypass and effect.

  • Two-way power operation, using 9V alkaline battery or optional AC adaptor.
    (9V alkaline battery: more than 34 hours, 9V manganese battery: more than 17 hours)
    Easy-access, tool-free battery compartment.

  • A stabilized DC to DC converter constantly provides stable DC9V power.
    Battery voltage drop and fluctuation of AC power source do not affect the tone and function.
