The TUBECORE 500 is a full symmetric transformer balanced 500-series compressor. The structure is based on the typical vari mu solution. The TUBECORE 500 is a true tube mono compressor where compression is achieved using the remote cut-off of tube biasing. Could be used as a mono tracking compressor or (as a matched pair) as an advanced mastering tool.
Every single TUBECORE 500 is hand made with high quality, matched components (1% metal film resistors, 2.5% Wima caps). It is equipped with JJ tubes and individually calibrated to give you the unique and unspoiled experience of one of the best Vari-mu compressors in history. We have spent hundreds of hours designing the TUBECORE, to make sure that it is as simple to use as it is versatile. Not only for harmonically rich drums and guitars, but also for huge vocals and bass instruments. Two audio transformers (IGS Custom) have been used to provide excellent performance.
