Airwindows has released Single Ended Triode, an effect plug-in for Mac.
Another must have- Single Ended Triode is a universal binary AU plugin with three separate unusual and useful modes of distortion. Asymmetrical, class AB and class B. A versatile sonic seasoning kit completely under your control!
Single Ended Triode is such a great idea that I’m selling it for $50, not $60, to get it into more people’s hands. It’s like Density, in that it’s a really fundamental building block of sound, implemented really cleanly so you’re not screwing anything up by overprocessing.
