Classic Equalizer EQP-1 is a dual-channel passive EQ based on the legendary Pultec EQP-1


The Classic Equalizer EQP-1 was built after the model of classic vintage equalizers with passive components (condenser and inductor) in the EQ section which accounts for it´s special sound.

The EQP-1 consists of three parts: Bass Boost and Cut, Treble Boost with adjustable bandwidth and a High Frequency Cut.

WHAT IS THE TUBE STAGE DOING
The Classic Equailzer is equipped with a tube stage and high quality input and output transformers.

Beside the open and airy sound of the equalizer the signal will get more density and additional presence by the tube and the transformers. The low end becomes more transparent and defined. The highs will sound more rounded and pleasant to the ears.

This effect will already take place as soon as the device is in the signal path and even if the equalizer is not used.
