The IGS Audio Rubberband 500 Mastering Edition is a 500 series stereo passive EQ. It is inspired by the legendary Pultec EQ and designed for mastering applications.

The IGS Audio Rubberband 500 Mastering Edition features a Class A driver circuit.  It uses a Carnhill input transformer and Edcor output transformer. Besides it uses top quality ELMA switches on all controls for precise setting and easy recall.

By contrast the filtering section is 100% passive and emulates '60s analogue EQ's. Unlike the original Pultec, this EQ has separate frequencies for low boost and low cut. This offers much more flexibility that mastering and mixing engineers will appreciate. It also boasts a far greater choice of frequencies to focus on problematic regions.

The Rubber Band mastering EQ will impart a wide range of distinctive colours to a mix. Mastering engineers will also love the technical performance of this EQ.
