The core circuitry that this module was based on is still the custom op amp like its parametric brothers. So the same sonic character is retained here, but the graphic approach makes it quick and easy to dial in a particular shape, which is clearly shown by the ten vertical sliders.
This module is handy when you need to make EQ adjustments on larger parts of the spectrum instead of a restricted area. Boosting or cutting several bands at once will radically alter the sound of a track, be it a thin, weak snare that needs low end or a dull vocal that needs to be opened up.
This module is a great complement to the EQ PA and EQ PB parametric modules.
Modeling with extreme accuracy all of the signal path and the high headroom allowed by the custom op-amp and the output transformer of the original hardware made possible to maintain all of the analog character and subtle harmonic distortion that makes this modules so "beefy". Such feature is the key to its big and bold "American sound" that is clearly recognizable in hundreds of A-list mix productions.
On top of this, the reciprocal nature of the EQ PG’s bands, and its fixed frequencies, easily allows it to "undo" a boost or cut operation on an already processed file.
