Smaolab has released version 1.1 of its VST/AU/LV2 dynamic tube processor plug-in, Yamatube.
Yamatube is based on a baxandall equalizer + two secret analog tubes. It can increase sound space as well as produce a nice saturation sound. You can at extreme values create a sort of Tube Clipper. Yamatube includes a soft limiter.
Version 1.1 adds a Mix knob and a bug fix relating to the sound level dropping drastically under certain conditions.
The Pro version can be download through the KVR Marketplace. A functional Demo is available from their website.
