TB Audio

CMOS Steezer Inverter Fuzz Colour Kit (Discontinued)

The CMOS Steezer is discontinued as of May, 2016.

The CMOS Steezer from TB Audio brings a unique color of distortion to your mixing toolbox. Well known in the guitar pedal and modular synthesizer worlds but rare in pro audio, the CMOS inverter topology yields a soft, tube-like distortion that retains the character of the original signal. The Steezer tailors this distortion to the demands of pro audio, with subtle character at normal levels and raunchy fuzz when driven hard.


  • CMOS inverter fuzz
  • Pleasant distortion character maintains the signal's identifying details
  • Compatible with the Colour 500-Series Palette
  • Black PCB
  • Full, step-by-step assembly instructions

The samples below demonstrate the sound of the CMOS Steezer at various Saturation levels.
