The idea of some live mix polish, simple hardware mastering for modular/dawless/live set ups or simple a characterful parallel processor and DI box is certainly an exciting one. The Golden Master from Endorphines builds on inspiration from classic ‘90s mastering rack units and their experiences with live performances with synths & modular and puts together a box of multi band compression, EQ and multi band stereo mid/side based stereo enhancement.
This pedal version offers presets, sidechain or expression pedal inputs, stereo ins and outs, per band mutes (handy for setting up each band but also as a performative frequency dependent set of mutes!) and parallel processing (i.e. dry/wet mixing) options.
