Rubber Bands

Have you ever dreamt about your own Pultec style EQ?

Great, here's your stereo unit.
Many sound engineers believe that the passive equalizer is a cure for all digital evils. A distinctive characteristic of the IGS Audio Rubber Bands Equalizer is its stereophonic structure, where the manual selecting of components with an accuracy of 1% allows for perfectly synchronous manipulation of both channels. The inputs and outputs are transformer balanced.

Organic Amp.
The Rubber Bands EQ consists of two blocks: The first block is a classic passive filter well known from the EQP-1 Pultec equalizer. The second block is a specially designed two-stage tube amplifier called Organic Amp.

Sound shape.
The new design includes a bypass relay, which allows you to instantly compare the results of your work. The equalizer has been divided into 4 sections: 2 for bass and 2 for treble. Frequencies are being selected with stepped switches. Boosting and cutting are controlled continuously. Manipulators featured are Bass Boost, Bass Cut, High Boost (with the choice of Q) and High Cut. Interactions of filters that allow simultaneous boosting and cutting of certain frequencies can produce amazing sound effects.
