Electro Harmonix Operation Overlord Allied Overdrive - Secondhand

Full Description

Normal vs Boost

The Operation Overlord enables you to use the pedal in two modes: Normal, or Boost. The Normal mode uses three JFET gain stages to achieve a tube amp-style overdrive for low to medium gain sounds. When in Normal mode, you can use the Gain control to determine the precise amount of overdrive you desire. The Boost mode engages a classic pedal-style overdrive circuit before the JFET stages for increasing the overall distortion and dirt.

The Boost mode can be engaged via 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 is fed into the main JFET circuit. The Boost circuit can also be configured to operate on its own without the JFET gain stages, by locating the slide switch inside the pedal and sliding it to the option labeled "BOOST INDEPENDENT." This disables the Gain and Boost control knobs and allows the other controls to function normally when only the blue LED is lit, and the red LED is not. Engaging the normal mode (noticeable by the red LED being lit), the pedal will function as normal.

Controls

• Gain: Controls the amount of overdrive/distortion. Turning clockwise increases the amount of input gain.
• Boost: This controls the amount of extra gain fed into the main circuit when the Boost and Normal modes are engaged (both LEDs lit). Turning clockwise increases the amount of distortion.
• Dry: Mixes a clean unaltered signal with the distortion produced by the pedal. At minimum, the output will be completely overdriven with no dry signal. At the maximum position, the signal will be completely dry with non of the Operation Overlord's overdriven/distorted signal. This is ideal for maintaining the harmonic integrity of your playing, which is perfect for keyboard or bass guitars. It's also great for stacking the Operation Overlord with other drive pedals, or if you are playing through an overdriven amp.
• Input Lvl: Controls the overall input level of your instrument into the Operation Overlord. Use to see an appropriate gain level for a variety of different instruments. Setting the switch to HI is recommended for low level instruments, such as guitars with single-coil pickups or vintage electric pianos. Setting the switch to NORM is recommended for guitars equipped with humbuckers and most modern keyboard workstations. Use the LO setting for high output instruments such as some synthesizers and boosted guitars.
• Bass: Active control for the bass frequency range.
• Mid: Active control for the middle frequency range.
• Treble: Active control for the treble frequency range.
• Vol: Controls the overall volume output of the Operation Overlord. Turning clockwise increases the overall output level.
• Bypass Footswitch & Red LED: Toggles whether the Operation Overlord is engaged or in buffered bypass mode. When the pedal is engaged, the red LED will be lit.
• Boost Footswitch & Blue LED: Toggles Boost mode on and off. When Boost mode is engaged, the blue LED will be lit.
• L / R Input Jacks: 1/4'' jacks for providing either mono or stereo input. Using the L input will transfer the signal in mono.
• L / R Output Jacks: 1/4'' jacks for providing either mono or stereo output. Using the L output will transfer the signal in mono.
• 9V Power Jack: For connecting the EXH9.6DC 200mA AC adapter into the top of the pedal. The Operation Overlord requires a minimum of 90mA with a center negative plug.

Features

• Silent foot-switchable Normal and Boost modes to provide distortion/overdrive tones ranging from mild to heavily saturated
• The Normal mode uses three JFET gain stages to deliver tube amp-style response and sonic characteristics
• The Boost mode adds a classic pedal-type overdrive circuit before the JFET gain stages to deliver even more dirt
• Three-position switch allows you to select the correct input level for your instrument
• Ideal for Guitar, Bass, Keyboards, and almost every other electronic instrument
• Active EQ with Treble, Mid, and Bass controls
• Dry blend allows you to add your dry signal to your wet signal for even more tonal versatility
• Comes complete with a standard EHX 9.6DC200mA power supply
• Buffered bypass
