The Sontec MES-432C is a rare and prized analog mastering equalizer.

Developed by Burgess MacNeal and George Massenburg, the Sontec EQ was one of the first parametric EQs created and to date remains highly sought after, particularly for mastering.

The most amazing feature of the Sontec EQ is its musicality. Unlike many parametric EQs, which can have as much a negative as a positive effect on your audio, the Sontec is hard to get a bad sound out of. To this day it is heralded as George Massenburg's most musical-sounding EQ design.

The only Sontec EQ in Queensland, and one of only a small number of Sontecs currently in use throughout Australia, is right here at Matthew Gray Mastering.
