Voxengo Tube Amp (64 bit) for Windows

Tube Amp is an audio effect AU and VST plugin that applies asymmetric tube triode overdrive usually found in single-tube microphone pre-amp boxes. The sound this plug-in produces varies from a mild "warm" overdrive to a fuzzy distortion.

Tube Amp also includes a -6 dB/oct low-pass filter that is built-in into plug-in's valve modeling equation, and can be used to imitate a lower-quality tube triode. Beside that, Tube Amp has a switchable output saturation stage which can be used to additionally overdrive the output signal.
