Offering the same warm, open-sounding overdrive as the OSD-9 but with a more pronounced high-frequency response, the OOD-9 is perfect for "livening up" a dark-sounding guitar or amp.
The OOD-9 reacts smoothly to input level changes, offering a highly interactive response to player dynamics. Perfect as a stand-alone dirt box or for pushing an amp, the OOD-9 can also be stacked with other OD's to add clarity and character to their tone.
The OOD-9 offers up all these classic sounds in Maxon's indestructible, industry standard 9-Series chassis. Modern-day utility features such as mechanical true bypass switching and a voltage regulator have also been added to provide smooth, consistent performance.
Providing mild, transparent overdrive that doesn't step all over your original tone, the OOD-9 Organic Overdrive truly lives up to its name.
The OOD-9 takes Maxon's resurrected OSD-9 circuit and replaces the NOS 741 Op Amps with current-production NJM (JRC) 4558's.
The OOD-9 signal path starts with a 2SK246 jFET buffer which provides a high input impedance and low output impedance into the 1st Op Amp - a NJM (JRC) 4558. This 1st Op Amp is set up to provide a 20 to 120x gain in signal.
After the 1st Op Amp we have a pair of diodes to ground, just like classic boxes such as the MXR Distortion+, Pro Co Rat and Boss DS-1. From here it's into another NJM4558 with an amplification factor of 10 to boost the signal back to a high enough level to drive the input of an amplifier if necessary - a feature that the Dist+ and DS-1 do not offer.
From here the signal is routed to a 4558 Op Amp unity gain amplifier, a volume control voltage divider, and then another unity gain 4558 to provide a low impedance output.
The OOD-9 uses a NJM2374A Voltage converter to stabilize the operating voltage at 9 VDC regardless of the voltage level coming off the battery, providing a smoother, more consistent operation and tonality.
The OOD-9 features Mechanical True Bypass switching via a Fujisoku 4PDT switch - the input of circuit is switched to ground when bypassed.
NOTE ON POWERING THE OOD-9 - this pedal's voltage regulator IC requires a high inrush current of approximately 2000 mA upon startup. When using with a Power Brick such as the Voodoo Labs Pedal Power 2+, this pedal should be connected to a high current power jack when possible.
If it is not possible to connect to a high current jack, you can power the OOD-9 by leaving a battery in the pedal. Upon initial start-up, unplug the external DC power input cable, engage the pedal, and then plug the DC power input cable back in - the pedal will now power up normally off the external power supply until you power down your pedalboard.
