The Wampler Cory Wong Compressor is a dual-function pedal combining a compressor and a boost circuit. It is designed for both studio and stage use, offering features like an XLR output for direct connection to mixing desks or audio interfaces, and a ground lift switch to eliminate noise. The pedal features two independent footswitches, allowing you to engage the compressor and boost separately or together.
Controls Overview
The pedal features several controls to shape your tone:

- Compressor Controls: Volume, Sustain, Attack, and Blend.
- Tone Control: Brian Wampler’s signature tone control to add sparkle and chime.
- Boost Control: A single rotary control to adjust the amount of boost.
- Boost Mode Switch: Toggles between a flat frequency boost and a rich, saturated mid boost.
- Comp On Switch: Permanently engages the compressor circuit.
- Footswitches: Independent switches for 'Compress' (left) and 'Boost' (right).
Signature Settings
The manual provides specific settings to achieve Cory Wong's signature sounds:

- The Cory Wong Signature Tone: A clean, powerful, and rich tone. Boost is set to Flat mode.
- Lead Tone: Higher sustain, with Blend and Attack dialed back. Use the boost in Mid mode for extra bite.
- Just hit the Tape!: Settings optimized for studio recording, suitable for both amplifiers and direct DAW/recording desk connections.
Connections and Power
To ensure proper operation and avoid damage to the pedal:
- Power: Use a 9V DC power source only. Do not exceed 9V DC, do not use center pin positive adapters, and do not use AC power. The pedal draws approximately 30mA.
- XLR Output: Connect directly to a PA system, mixing board, or audio interface using a separate XLR cable.
- Ground Lift: Engage this switch if you experience unwanted ground noise when using the XLR output.
