OVERDRIVE PRO PLUS (OD-9Pro+)
Overdrive based on classic OD-9
Switchable 9- or 18-volt operation (runs on 9 VDC)
More Gain and Low-End (18-volt setting)
Mid Boost Switch add +3 dB @ 800 Hz
NJM4558 (JRC) Op Amp
True Bypass Switching
The Nine Series Overdrive Pro+ takes Maxon’s classic OD-9 circuit and
serves it up with two side orders of Whoop-Ass in the form of 9/18 volt
operation and a Mid Boost switch.
In 9-volt setting the Pro+ sounds and functions like the standard
OD-9 with the added option of a healthy +3 dB of midrange boost at
approximately 800 Hz (actual frequency is dependent on Control settings)
– great for cutting through a band during solos.
When set to 18-volts the OD-9 Pro+ becomes an 800-pound Gorilla,
offering up beefier lows, tighter saturation, improved dynamics and a
chunky, aggressive pick attack that will make your amp sound and feel
like it just took a Viagra. Switch on the Mid Boost in this mode and
let your solos breathe fire.
Don’t just play like the pros – play with the Pro Plus.
TECH TALK:
The OD-9 Pro+ starts with a jFET buffer which simultaneously offers high input impedance and low impedance into the rest of the pedal – this helps to preserve high-end clarity in the signal.
The first tone stage is the Mid Boost feature: A switchable Op Amp
with clipping diodes in the feedback loop. When this stage is not in the signal path the pedal behaves like a standard OD9. With this stage in the path it adds subtle gain and definition to the sound, similar to a cascading gain stage.
From here it’s on to the standard OD-9 circuitry: A clipping Op Amp
with diodes in the feedback loop that clip the signal gradually as well
as a high pass filter that keep the low frequencies from being distorted
as much as high. Next there comes a passive LP filter and then an
active tone stage. After the tone stage it’s through the Volume pot, an
Op Amp boost stage which bumps the signal 3X and then sends it to the
output.
The Pro+ also utilizes an NJM2374A voltage conversion chip that
changes the 9V power input into 9V+ and 9V-, increasing the headroom of
the Op Amps (9V to 18V swing) and giving a bigger, chunkier sound to the
overdrive.
The OD-9 Pro+ features Mechanical True Bypass switching via a Fujisoku 4PDT switch - Input is switched to ground when bypassed.
NOTE ON POWERING THE OD-9 Pro+ - 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 OD-9 Pro+ 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.
