Maxon OD9 Pro+ Overdrive Pedal

Maxon OD9 Pro+ Overdrive Pedal
At long last, an overdrive unit that meets and exceeds the demands of the market and deservedly takes its place beside the legendary 808. While developing the OD-9 Pro+, Maxon enlisted the help of an advisory board of professional guitarists to create a new classic overdrive pedal.

Starting with the basic OD-9 circuit, the OD-9 Pro+ adds a low-noise NEC uPC4570 OP-Amp in the output stage that allows for less compression and a more balanced frequency response. Increased Output level and true undistorted signal at zero Drive are further benefits of this component swap.

The OD-9 Pro+ offers a switchable Boost feature that bumps the midrange by +3dB, and the overdrive level by +10dB, creating a thicker, slightly compressed overdrive tone. Bright, Singing sustained notes and improved harmonic response are further benefits of this new feature. If you always felt that the OD-9 was a bit anemic, the Pro+ Boost Mode is just what the doctor ordered.

The Pro+ also features the addition of a stabilized DC-DC voltage converter in the power circuit of the Pro+. This voltage converter bumps 9 volts up to 18 volts, offering a much wider dynamic range and increased head room. Operating voltage is switchable between 9 and 18 volts, offering a choice between the classic OD-9 tone and this newer, full-frequency tone.

The OD-9 Pro+ features True Mechanical Bypass switching courtesy of a 4PDT switch. With the combination of these new features and circuitry, the Maxon OD-9 Pro+ effectively functions as a 4-voiced monster, offering everything from the classic, bluesy tones of the original 808 to the searing saturated chunk demanded by today’s extreme metal music.
