IGS Audio Rubber Bands is a stereo EQ, good on vocals, guitars and strings – adding fat low end and crispy high frequencies.

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.

The new design includes a bypass relay, which allows you to instantly compare the results of your work.

Rubber Bands 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.

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.
