Suhr Koji

Suhr Koji Compressor is a versatile analog compressor, designed to offer a wealth of vintage and modern style compression effects without compromising your tone. With a simple twist of the Mix control, or flick of Koji’s Voice switch, you can easily create a limitless range of compression effects. Whether you choose subtle, transparent compression for smoothing out your rhythms, or dial in warm and squishy tones to take you into R&B and Country territory -the Koji Comp is possibly the last compressor you will ever need.

The pedal has 4 control knobs. The Comp knob determines the amount of compression (gain reduction) applied to your signal path. The Level knob adjusts the overall output level of the Koji Comp. Use this control to compensate for the amount of Compression/Gain Reduction applied to your signal path. The Attack knob determines how quickly the compressor responds to signals above a desired threshold. The Mix knob varies the ratio of dry to compressed signal from 10% – 100%.

The Voice switch offers three voicings. To the left offers a boost to the upper midrange frequencies to bring out the attack in your picking. In the middle you get a transparent (flat) frequency response. To the right offers a boost in the upper midrange and treble frequencies – for a smooth, glassy, top-end sweetness.

More than simply indicating the pedal is turned on, the LED gives you visibility into the amount of compression you’re using. The LED will display one of three colors, indicating the amount of Gain Reduction based on the ratio of your instrument’s signal and the level of compression in your signal.

Because compressors are commonly found early in the signal chain, we’ve included a high quality, transparent sounding, buffer. Via an internal switch, you can choose to have Koji operate in true bypass, or buffered bypass modes. The FX Link connector allows the pedal’s switching function to be controlled from an external switch, pedal board, loop switcher, or any other custom interface. Koji incorporates a unique battery monitor that alerts the user to low battery conditions. In addition, the battery monitor will automatically switch the pedal to True Bypass if the battery voltage is too low for the circuitry to correctly operate.
