Wave Arts have announced the launch of Tube Saturator Vintage, a free VST/AU effect plugin reissue of their original Tube Saturator tube amp model.
Tube Saturator Vintage uses a circuit simulation technology that faithfully reproduces the sound of a dual triode preamp. The circuit simulation technology is very CPU intensive, that’s why Wave Arts have developed its successor, Tube Saturator 2 – a more efficient plugin. But some users also requested the sound of the original plugin, hence Wave Arts have re-released it as freeware.
Tube Saturator is the world’s most accurate real time tube amp plug-in. Unlike other tube simulators, which use radically simplified models, Tube Saturator uses state of the art circuit simulation technology to capture every nuance of an analog circuit. With circuit simulation, the analog schematic (consisting of the individual resistors, capacitors, tubes, and so on) completely defines the signal processing. The schematic is converted into a system of non-linear differential equations which is solved at each sampling period, in realtime. That’s mathematical talk for “it sounds exactly like the analog circuit”.
Tube Saturator is, in fact, a basic circuit consisting of a Baxandall type three-band EQ feeding two 12AX7 triode preamp stages, similar to preamp stages you’d find in a guitar or high fidelity amp, and hence you can get the same distortion and tonal characteristics that you’d get from saturating a real tube preamp. The circuit simulation technology is extremely CPU intensive and a fast computer is recommended to run the plug-in.
Increasing the Drive control increases the (digital) input gain while decreasing the (digital) output gain, so you can easily adjust distortion levels. The FAT switch changes the bias circuit of the first preamp stage to increase gain and saturation.
You can use Tube Saturator to add a bit of analog warmth to recordings, or increase the drive for some distortion. You can also use it as a saturating peak limiter.
Wave Arts Tube Saturator Vintage is available as an instant download (9.41MB compressed ZIP file containing the installer). The first time you open it, you will be asked to register the plugin: simply add your name and email address and that’s it.
