EarthQuaker Devices – The Warden – Optical Compressor

1. Tone: This pedal was designed to slightly color your tone, and the coloration can be dialed-in to your taste. Counterclockwise is treble cut, clockwise is treble boost. The tone is nearly flat around 11 o’clock.

2. Attack: This controls how quickly the compressor reacts and starts leveling the signal. All the way counterclockwise is a fast, nearly immediate reaction. Turning the attack clockwise slows the reaction time.

3. Release: This controls how long it takes the signal to raise back up to the level determined by the Sustain and Ratio settings. All the way counterclockwise is a fast release and the release time slows as you turn it clockwise.

4. Level: This controls the overall output and is affected by the Sustain and Ratio settings. There is no specific unity setting; adjust to taste when you find your perfect compression setting.

5. Ratio: This determines how much the gain reduction affects the signal. All the way up is full compression and the compression is reduced as you turn this counterclockwise which allows more of the boosted, less-compressed signal to come through. There are no defined ratios here.

6. Sustain: This is the heart of The Warden. It controls how hot the signal is, which changes the dynamics of the compression. The Warden is a feedback-style compressor; the hotter the signal, the more active the compression. Very little Sustain= very little compression, less active Attack and Release and a cooler signal. Max Sustain= heavy compression, longer sustain, hotter signal and more lively Attack and Release.
