Maxon OD-9 Pro Plus Overdrive Pedal
Starting with the basic OD-9 circuit, the Maxon OD-9 Pro Plus 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 Maxon OD-9 Pro Plus 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 Plus 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 pedal tone and this newer, full-frequency tone
The Maxon OD-9 Pro Plus Pedal features True Mechanical Bypass switching courtesy of a 4PDT switch. With the combination of these new features and circuitry, the Maxon OD-9 Pro Plus 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.
