Comp670 is Overloud's recreation of a very rare, legendary tube compressor. It has a unique and distinctive tone thanks to the large number of transformers in the signal chain which give it a very warm tone.

Key Features:

  • Hyper-realistic simulation of the original unit thanks to 4th generation dsp technology
  • Three different example units recreated, in one plug-in, each with unique dynamics and coloration
  • Built-in Parallel Compression
  • Soft-knee / hard-knee control with the additional DC Threshold parameter
  • Built-in filters on the Sidechain
  • Meter Calibration: Calibrate the VU meters at 4 different sensitivities
  • Multilevel undo-redo
  • A/B Comparison
  • Lots of presets designed in real mixing sessions
  • Scribble Strips: take notes anywhere on the plugin panel


Comp670 extends the features of the original hardware: It combines the flexibility of the digital world with the sound character of analog processing.

Model Selection


Select one of the three units sampled in London, Los Angeles and Milan studio, each with its own personality and unique tone.
Sidechain Filter


You can tweak the Low Cut filter on the Sidechain to reduce the compressor sensitivity to low frequencies. This is particularly useful to control the amount of "pumping" effect.
Parallel Compression


Parallel compression is a powerful mixing technique which helps improve the overall impact of the track while leaving the transients intact. It is achieved by summing the compressor output to the original track.


Every surviving example of this compressor has its own history and component tolerance, which gives each one a unique tone and dynamic response.

That's why Overloud sampled three different hardware units, each serviced multiple times since the ‘50s (found in London, Los Angeles and Milan studios), and packed them into one powerful plugin.
