The Maxon OOD-9 Organic Overdrive Pedal is a versatile and high-quality effects pedal designed for guitarists seeking warm, open-sounding overdrive with a pronounced high-frequency response. The pedal features a 2SK246 jFET buffer at the beginning of the signal path, providing high input impedance and low output impedance into the first Op Amp – a NJM (JRC) 4558. This Op Amp is set up to provide a 20 to 120x gain in signal. The signal then passes through a pair of diodes to ground, similar to classic boxes such as the MXR Distortion+, Pro Co Rat, and Boss DS-1.
The OOD-9 also includes a NJM2374A Voltage converter to stabilize the operating voltage at 9 VDC, ensuring a smoother and more consistent operation and tonality. It features Mechanical True Bypass switching via a Fujisoku 4PDT switch, and its voltage regulator IC requires a high inrush current of approximately 2000 mA upon startup.
Key technical specifications include:
- Input Impedance: 500K Ohms
- Output Impedance: 10K Ohms or less
- Maximum Gain: 41.5dB (700Hz)
- Equivalent Input Noise: -107dB or less (IHF-A)
- Control: DRIVE, LEVEL
- Operating Voltage: 9V
- Power Consumption: 18mA/DC 9V, 18mA/DC 10V
- Dimensions: 74 (W) x 124 (D) x 54 (H) mm
- Weight: 580g (including battery)
The OOD-9 Organic Overdrive Pedal is an updated version of Maxon’s first Overdrive - OD880, circa 1977, and is suitable for use as a stand-alone dirt box, for pushing an amp, or for stacking with other OD’s to add clarity and character to the tone. It is housed in Maxon’s indestructible, industry- standard 9-Series chassis and features modern-day utility features such as mechanical true bypass switching and a voltage regulator for smooth, consistent performance.
