The GML 8200 Parametric Equalizer is the reference standard parametric EQ from the engineer who invented the concept. The 8200 is a fifth generation progressive design, the result of ten years of creation and precise listening analysis. Incorporating the exclusive GML op-amp, this unit has no tantalum or electrolytic interstage or output coupling capacitors. The result is the most natural of equalizers, with minimum artifacts and signal modification.
