Signal Perspective releases Grindbox Mk2

Signal Perspective released a free (actually donationware) plugin.

It's called Grindbox, it is a saturator for Mac, Win and Linux, (VST3 & AU).

From the product page:

Grindbox is a distortion plugin based on some waveshaping techniques I came up with in the early days of my audio processing endeavour, wrapped in a modern framework with 384kHz oversampling and a fancy interface.

It can be used as a simple amp simulator for bass and guitar, or as a versatile saturator capable of adding slight coloration, behave like an exciter, or completely destroy the signal.

Speaking of features, the most noticeable are:

Continuous morphing between cabinet simulations
Various static transfer functions
Slew rate distortion
Variable topology settings
Microphone simulation
384 kHz oversampling
Built-in limiter
Resonant LPF
Auto Gain
Tilt EQ
