IGS Audio Tubecore – Mastering Edition (Stereo Tube Bus Compressor)

I'm selling my IGS Audio Tubecore in the Mastering Edition in very good condition. The unit was used exclusively in a smoke-free studio and is fully functional.

The IGS Tubecore Mastering Edition is a high-end, fully discrete stereo vari-mu tube compressor from the Polish boutique manufacturer IGS Audio — inspired by the legendary Fairchild sound, but with modern features and a character all its own. This Mastering Edition differs from the standard version through precisely stepped controls on all knobs, allowing for perfect recall and absolutely identical channel matching in stereo operation — essential for professional mastering work. Sonically, the Tubecore delivers that unmistakably smooth, musical, and "glueing" vari-mu sound with the characteristic tube warmth: dense, punchy, and three-dimensional mix bus sound without destroying transients. Perfect for mastering, stereo bus compression, drum bus, or as a "glue" compressor that adds cohesion and depth to a mix. Features like switchable sidechain filters, a mix knob for parallel compression, and various ratio settings make it incredibly versatile. Standard 19" rack format with a high-quality metal chassis.
