One of the finest mastering compressor ever created!
The TUBECORE 3U is a fully symmetric transformer balanced stereo mastering compressor. The structure is based on the typical vari-mu solution. Apart from the classic INPUT, THRESHOLD and OUTPUT controls it introduces switchable high pass filter in the sidechain, parallel compression (MIX knob), independent ATTACK and RELEASE switches and user replaceable tubes accessible from the back of the unit.

Every single TUBECORE 3U is hand made with high quality, matched components (1% metal film resistors, Wima caps). It is equipped with 6N1P-EW NOS tubes and individually calibrated to give you the unique and unspoiled experience of one of the best vari-mu compressors in history. It is equipped with Carnhill and Sowter audio transformers.

The Tubecore 3U adds density and dimension to your mix in a magical way. The Tubecore was designed as a studio mastering compressor. It is built using the 3U enclosure, which gives necessary front panel clarity and makes it easier to replace tubes located at the back. This design is based on the possibility to replace tubes. The user decides how the device should sound. The sound can be changed by changing the tubes in the back of the device. You can achieve the following effects:

  • 6N1P-EW – standard set of tubes, “standard” compression
  • 6BC8/6BZ8 – tight, transparent, punchy compression
  • 6386 – legendary compression, by famous twin triode
  • 5670 – deep and dark tube compression


  • Sidechain HPF,
  • MID/SIDE Processing,
  • WET/DRY Mixer,
  • All stepped manipulators,
  • Engineer’s custom tube set.
