The Burier is a saturation and filter plugin designed for use on a variety of applications. It has a saturation stage, followed by a pair of resonant filters, output attenuation, and dry/wet mixer.

The filters have 12 dB of attenuation per octave. They are IIR (Infinite Impulse Responses) filters with a TPT (topology-preserving transform) structure. Their behavior is based on the analog SVF (state-variable filter) circuit, which is a second-order RC active filter.

Not only can you add it to your guitars, but also it does its job tremendously well on pianos, drums, synths, vocals, and basses. You can go from light overdrive to a hard punchy saturation.
