Clarity Haven is an amplifier simulator plugin for guitar (acoustic or a distorted electric).
The main concept is overuse of oversampling. In the beginning of the circuit there are 3 2X oversamplers in series, with another 3 in parallel, and those all go into another 2x oversampler. This whole bunch of oversamplers is again repeated at the end of the chain of stuff. It all makes a big wall of mush.

ATKGuitarPreamp is a guitar preamp plugin, modeling the inverter input stage of a Vox AC30 followed by a JCM800 tone stack.
Just like a bass preamp, you can dose the amount of distortion, bass, medium and high frequencies. The final stage gives you the option of turning the volume up or down, as well as balance the dry sound with the processed sound.
It is built on top of AudioToolKit and JUCE.
