Axe-Fx Standard and Ultra

The first generation of the Axe-Fx consisted of two models. With the release of the Axe-Fx II in May 2011, Fractal has discontinued production of these models (End Of Life).
- The original Axe-Fx (now commonly known as Axe-Fx Standard) was released in 2006.
- In 2008, Fractal released the Axe-Fx Ultra, which doubled the processing power, added memory and Ultra-only effects.
Cliff: "I really wish I could update the Standard and Ultra but it is simply out of memory. There are literally 1309 words left (out of 128K) in the Ultra's EPROM. That's enough room for maybe one or two amp models and that's it. IR slots are limited by the size of the SRAM which is fixed. I'd like nothing more than to bring some of the Axe-Fx II modeling to those old products but it's simply not feasible." Source
Cliff: "The biggest difference between the two is that the Axe-Fx II has a lot more highs. The Ultra will sound dark (or some may say warm) in comparison. Compared to a real amp the Ultra will sound dark or muffled. Many people like this quality." Source
