Suhr Koji Compressor Pedal

Modern & Vintage Style Compression


The Suhr Koji is a 100% transparent analogue compressor pedal that works brilliantly no matter your desired sound. If you're looking to add sustain and level out your sound or get those squashed country or R&B tones, the Koji can handle it.

A lot of compressors pedals only focus on one type of compression. If you like to switch between styles, you may need a couple compressors on your board. The Koji works with both modern and vintage style sounds, as well as clean or overdriven tones.

Transparency or Warmth

Dial in a wide range of sounds thanks to the voice control at the top of the pedal. The first position lets you access transparent compression perfect for modern high gain, maintaining the same sounds from your amp, but pushing it in a different way. The vintage-voiced mode adds warmth and character that's perfect for a country picking old school style.

All The Control You Need

The Koji has four main controls and a very cool feedback function. These four knobs Comp, Level, Attack and Mix each have a decent amount of range to them and are all essential for dialling in the perfect compressor sound.

Comp is the amount of compression you want to put through your signal turn to the left for a more subtle smoother effect and to the right for a more obvious squished effect. Level is simply the output level of the pedal. You can set it up so you get a partial boost with the level control but normally you just find unity and leave it.

Attack controls how quickly the compressor kicks in after detecting the signal. This control is how you get that classic chicken picking. Mix is your wet/dry control. Want a strong compressor but only applied to half of your signal? This is how you do it.

Instant Feedback

You can see exactly what your Koji Comp is doing at any time thanks to the multi colour LED. Green means little to no compression, amber is medium compression and red is fully compressed. Don't be scared of the red LED though some seriously sweet sounds are waiting to be found.
