Electro-Harmonix OPERATION OVERLORD Manual

OPERATION OVERLORD
Stereo Multi-Instrumental Overdrive
Congratulations on your purchase of the OPERATION OVERLORD, an advanced,
full-featured stereo overdrive and distortion pedal. With the OVERLORD's broad
range of options and controls you can dial in great drive sounds for keyboards,
synths, guitars, basses, and more. Active 3-band EQ controls, footswitchable
BOOST mode, and a dry blend provide versatility for different tones and
instruments. The OVERLORD also features two independent distortion channels
for use with stereo setups. Whatever your rig, use the OVERLORD to dial in your
tonal inspiration.

- MODES OF OPERATION: NORMAL VS. BOOST -

The OVERLORD operates in two modes: NORMAL and BOOST. The NORMAL
mode uses three amp-like JFET gain stages for low to medium gain sounds.
When in NORMAL mode, use the GAIN knob to control the amount of overdrive.
The BOOST mode adds a classic pedal-style overdrive circuit before the JFET
stages to increase overall distortion. BOOST is engaged with the BOOST
Footswitch and is active when the blue LED is lit. In BOOST mode, both the
GAIN and BOOST knobs are active, and the BOOST knob controls how much
additional gain from the BOOST circuit is fed into the main JFET circuit.
- USING BOOST MODE AS AN INDEPENDENT PEDAL –
The OVERLORD's BOOST circuit can also be configured to operate on its own,
without the NORMAL mode's JFET gain stages. To enable this, remove the 4
screws on the bottom of the OVERLORD and locate the slide switch at the
bottom of the PCB. Being careful not to touch any components, slide the switch
in the direction labeled "BOOST INDEPENDENT."
When independent BOOST mode is enabled, the BOOST circuit is active by itself
when the BOOST LED is lit and the BYPASS (red) LED is off. In this setting, the
GAIN and BOOST knobs are disabled. All other controls function normally. When
NORMAL mode is engaged (red LED lit), the pedal functions as usual, with the
BOOST mode feeding into the JFET gain stages.
