Yeks Guide to the Fractal Audio Drive Models
About the Guide
Forum member Yek (Alexander van Engelen) describes all drive types in the Guide to the Fractal Audio Drive Models.
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 to a PDF guide. The guide is updated periodically.
Brief information is also available on another wiki page.
Two versions of the PDF guide
Fractal Audio's modeling of drives has been improved in firmware Ares 3.02 and later for the Axe-Fx III. Gain, output level, characteristics and tone may have changed.
Tips and information for the current firmware for the Axe-Fx III may not apply to the Drive types in earlier firmware, including the 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 (firmware Ares 4.03), using a clean Band-Commander and a Euro Blue with varying amounts of gain.
The library also contains a couple of additional interesting presets.
