The Fredenstein Artistic EQ is a 500 Series Equalizer Module with 3x Semi-Parametric Bands. The Module is suitable for all Instrument groups and, like all Artistic Series Modules, is oriented towards the sound of classic Recording Consoles. The Colour Switch creates an additional sound variation with switchable Analogue Tube Simulation. Just like a Tube Circuit, this mode provides for a changed overtone behaviour and over-modulation at higher input levels.
