This is a Vid that a member over at the Fractal Forum put together to remove some of the fear of the more advance settings in the amp block. Remember those advanced settings are the equivalent of modding your amp. He does a really good job of explaining the controls simply, and showing you what they do. his tutorial is created for the AX8, but it fully translates over to the Axe FX. Highly recommend this vid, if you are an option paralysis person, or just wish you could replicate that hot rodded amp you heard at one time. I truthfully recommend all of his vids, the guy is great at dialing tones.
