Yeks Guide to the Fractal Audio Amp Models
From Axe-Fx II Wiki
The information on this page supplements the official manuals.
Forum member Yek (Alexander van Engelen) describes Fractal Audio's Amp models in his Guide to the Fractal Audio Amp models (PDF). The guide was preceded by a series of threads on Fractal Audio's user forum. Forum member simviz helped to assemble the contents of the forum threads into the guide. The guide is more complete than the forum threads and is updated periodically. If you find the guide useful, consider donating as explained in the guide.
Yek also created simple presets on his Axe-Fx II XL to demonstrate the Amp models. Download them here.
