Softube Reference EQs — emulations of vintage passive equalizers

Softube has released two separate VST plugins that closely emulate rare vintage tube devices. Designed for mastering, the plugins provide analogue colour and density without phase distortion.

Reference 1998 Equalizer uses a DSP engine to provide four passive parallel EQ bands for two channels. A high-headroom tube stage emulation adds subtle saturation. Shelving filters produce broad, smooth or more coloured curves and support the classic low-end mixing trick.

Reference 1956 Equalizer is modelled on a rare stereo version of the original hardware, with additional fixed frequency choices. Its advanced panel adds modern digital features: a built-in Mid/Side encoder/decoder, separate gain controls for left/right or M/S channels, and a Headroom knob.

Reference 1998 and Reference 1956 cost $100 each. The Reference Equalizers Bundle costs $150. Both equalizers support Console 1 Ready and can load directly into Softube Equalizers. They run on Windows and macOS in VST3, AU and AAX formats.
