Koji Comp

The Koji Comp 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.
