Emulating a vintage British Mic/Line preamp, BritPre is a free VST that comes with 2 modules with independent bypass and Lowpass and Highpass filters.

For starters, you can set preamp gain staging with various parameter knobs such as Gain, LPF, HPF, Phase (Phase invert on/off button), Mic (Mic Preamp switch), Output, and Analog Obsession (for turning on/off 4x oversampling).

Oversampling can really subtly compress and fatten the sound without adding distortion to instrument channel tracks and yet sound realistic and authentic.

If you want to spruce up your guitar or synth channel tracks with warm and subtle saturation, look no further than the SGA1566 preamp that can add “dirt” with tube overdrive to your tracks.

Not to mention, the SGA1566 is CPU-friendly and and works well for ambient mixes that use a lot of reverb and delays thrown in to a good measure.
