Yeks Guide to the Fractal Audio Drive Models
About the guide
Forum member Yek (Alexander van Engelen) goes into detail about every Drive model in his Guide to the Fractal Audio Drive Models (PDF).
The guide was preceded by his series of threads on Fractal Audio's user forum. Forum member Simviz assisted with migrating the contents of those 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 versions 3.02 and Ares 10.0. 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:
Download demonstration presets
Simple presets are provided to demonstrate many of the Drive models.
The presets were created on the Axe-Fx III with firmware Ares v10, using models of the Morgan AC-20 and Bogner Ecstasy Blue amplifiers.
If there's no sound, the Cab block may be linked to an empty user cab.
