Yeks Guide to the Fractal Audio Drive Models
About the guide
Forum member Yek (Alexander van Engelen) describes each Drive model in his Guide to the Fractal Audio Drive Models (PDF).
The guide was preceded by a series of threads on Fractal Audio's user forum. Forum member Simviz assisted with migrating the contents of the threads into a PDF guide.
The guide is updated periodically.
Brief information about the Drive models is also available on this wiki page: Drive block.

Two versions of the guide
Fractal Audio's drive modeling has been improved in firmware Ares 3.02 and later. Gain, output levels, characteristics and tone have changed, depending on the model. So, tips and information for the current firmware may not apply to the Drive models in earlier firmware for the Axe-Fx III, AX8, FX8 and Axe-Fx II.
Because of this, two editions of the guide are available:
Simple presets are available to demonstrate many of the Drive models.
The presets were created by Yek on the Axe-Fx III with firmware Ares 4.03, using clean Band-Commander and dirty Euro Blue Amp models.
The library contains a couple of additional interesting presets.
