The Mad Professor Kosmos is a compact reverb pedal that offers a huge variety of sounds despite its pedalboard-friendly size. There are a total of eleven different reverb modes available, ranging from natural reverb of different sizes to a wide soundscape. With the "Time" knob you can determine the decay time of the reverb tail, while with the "Control" knob you can adjust a parameter based on the selected mode. Press and hold the button to create a Freeze or Swell effect based on the selected preset.
