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 $49.99.
Try the demo of this to see if it'll work for you! You're not allowed to use the demo for actual work. It politely mutes itself briefly every couple minutes, and that's the only thing it does to spite you. It won't expire or do anything to you, and when you get the actual plugin, throw away the demo and put the real version in its place and most software should replace saved instances of the demo with the real thing seamlessly, retaining any settings. Please support my cooperative, unhostile demos with sales of the real software.
