ToneLib TubeWarmth v1.0.0 VST VST3 AU SAL WiN macOS [FREE]

ToneLib TubeWarmth is a free tube saturation effect for producers and guitarists who want to give clean digital recordings a little grit and harmonic richness. Its processing combines gentle, tube-modelled overdrive with added even-order harmonics, helping dry signals develop a fuller tone and a more textured character.

Use it when an instrument sounds too clinical or needs some warmth without making heavy distortion the focus. The straightforward approach makes it a useful option for hobby producers exploring saturation, as well as guitar players looking for mild tube-style drive.

A real-time frequency spectrum display shows both the incoming and processed signals. This lets you compare their frequency content while adjusting the effect, providing a visual reference alongside what you hear.

TubeWarmth is available in 64-bit VST, VST3 and AU formats, with a standalone version for use outside a DAW. Windows users can load the VST versions in hosts such as FL Studio and Ableton Live; the AU version suits Logic Pro on macOS.
