uComp Diode Compressor Colour


  • Partial Kit
  • Step by Step Guide
  • Advanced

Inspired by the classic British diode compressor design, adapted to fit on a small board. Using miniature transformers that should not be underestimated in terms of sound. From subtle control to aggressive shaping with detailed transients, all while infusing the source with that vintage, warm tone.

The uComp is a diode compressor designed by Zombie Rec. We offer it as a partial kit for advanced builders. We provide a bill of materials, assembly guide, and the harder-to-find components. You will have to source the rest of the components yourself, and there is a little bit of SMD soldering.


  • Distinctive diode compression can be dialed in for moderate smoothing or heavy limiting.
  • Neutrik input and output transformers
  • Compatible with the Colour format
  • Full, step-by-step assembly instructions


  • PCB
  • Nylon standoffs
  • 8-pin Colour header
  • BC550 transistors
  • Neutrik transformers
  • The rest of the parts must be sourced separately. See the uComp Bill of Materials

Would Give It A Five, But....

the placement of the solder pads for the transistors made it unecessarily dificult to solder them! Unless there is some electronic and/or mechanical reason for putting the pads side by side and the transistors flush to the PCB, it would have made more sense to put them in a triangular patternnad leave the transistors slightlt proud of the board. Arcane, byzatine design and maddeningly difficult to install Q1,2,3 and 4! That being said if there is a V2 correcting this, would not hesitate to build another. HS
