IGS Audio Rubber Bands 500

Rubber Bands 500 is a passive equalizer absurdly reduced in size. This tiny module is equipped with transformer balancing on inputs and outputs (Carnhill) as well as a discrete power circuit. Of course the entire filtering section is passive and mirrors fully analogue equalizers from the 60s.
