Blue Eq is a detailed emulation of vintage-revisited semiconductor equaliser, inspired by legendary British devices. For the first time ever, this well known EQ will be available in-the-box, and with a gorgeous original GUI. Originally equipped with germanium, this EQ sounds thick & huge with its beefy bottom, musical mid-range and "expensive" air. Modeled after an incredible EQ heard on many hit records, this unit has both passive and active signal paths.

This meticulously created VST version will help you transform your tracks from near-perfect to amazing. The BLUE EQ features an accurately emulated selection of bands and frequencies you can choose from.

The Low Frequency Band with a range from 30 up to 220Hz, switchable from bell to shelf, the Mid-Range Band with frequencies ranging from 300Hz to 8300Hz, and the High Frequency Band, which features a bell and shelf mode, ranges from 3200Hz up to the highest point of 20.000Hz.

Beside the precise modeling of sound and features, you will also get authentic harmonic distortions that the original unit imparts so beautifully. This is a very unique and musical sounding eq, suitable for mixing, mastering, and any other creative sound processing. We call it "The Rock'n'Roll Box" because it is so full of character and creative sound shaping possibilities.
