Orange Kongpressor Optical Compressor Pedal

Instead of the usual FET circuit used in many compressor pedals, Orange went with an optical based circuit for the Kongpressor and packed it with expanded control options.

As expected of an opto compressor, this pedal applies effects in a smoother fashion, which gives a more natural sounding result. This can be good or bad depending on personal tastes, it is well appreciated by those who prioritize signal integrity.

It also houses quite a lot of controls, which allows for more tone personalization. This includes the usual attack and release knobs, a main volume knob which gives you up to 12dB of clean gain, a squash knob and an active chime control that serves as a pseudo tone control for shaping the higher frequencies.

Most of the positive responses for the Orange Kongpressor are from guitarists who are impressed with its sound, which many describe as organic or natural sounding. It gets a lot of praise for its transparency, and how it doesn't drown out playing dynamics too much. Control options are also well received, with emphasis on the volume knob which turns the pedal into a great sounding boost effect. Even experts like Trevor Curwen of Music Radar is impressed with the pedal, he describes it by saying: "This pedal gives you transparent, unobtrusive compression that offers positive enhancement of your signal."


Those who are looking for a compressor pedal that colors the sound, particularly for clean tones - will probably not appreciate the Kongpressor's transparent sound. There are also some who wish that the size of the pedal is a bit smaller. Aside from these, there aren't any consistent complaints about the pedal's functionality and build.


If you are looking to add subtle compression to your guitar signal, then the Orange Kongpressor is a worthy option.

Although this was previously on our recommended list, there are now more highly rated options available which you can see in our guide to The Best Guitar Compressor Pedals.
