Yeks Guide to the Fractal Audio Drive Models
About the guide
Forum member Yek (Alexander van Engelen) goes into detail about all Drive models 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.
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 for the Axe-Fx III and FM3. 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 most Drive models.
The presets were created on an Axe-Fx III with firmware Ares v15, using models of a Fender Deluxe Reverb and Plexi, and Legacy cab #103.
