(A month is like a year in Fractal firmware time )
I'm guessing 95-99% of Axe users has no idea WTF that is (even after Cliff's explanation) but are excited nonetheless. That distinguishes the product and company from almost everything else.The next will be even better, though, with the new bias excursion algo....
Doubtless this new bit will improve the feel and sound as things are driven harder, as that is when bias tends to get pushed around and play with the operating point of the tubes, which affects the harmonic distortion content even before the amp breaks over into outright distortion.I'm guessing 95-99% of Axe users has no idea WTF that is (even after Cliff's explanation) but are excited nonetheless.

In many other contexts someone proclaiming "there's this obscure thing I'm working on and it will be cool/awesome" would be pure snake oil or cork sniffing mythology or outright marketing BS. With Cliff it's real, even if it's subtle.
Bias excursion happens as you push an amp. It modulates the bias and plays with these 'static' settings dynamically in response to your playing. It makes compression as the bias shifts, and can, in extreme cases, trigger nasty blocking distortion.
John Mayer compared modelers vs ‘real amps’ and said that modelers just don’t have that ‘wapoosh’ like you get with a real amp, whereupon @FractalAudio promptly ‘wapoosh-ed’ the firmware to put that complaint to rest. He uses an interesting analogy in the interview about a sex doll vs a woman, if I recall correctly. Anyway, we have ‘wapoosh’ aplenty now, so it’s all good.
