I recall Jack Zucker commenting on this back in the Ultra days; that the pedals offered something special not reproduced within the Ultra. So, if I understand correctly, the circuitry of the guitar is "one" with the circuitry of certain (but only certain) pedals. Can this be made more specific? Is it only certain fuzz pedals that offer this desirable electronic interaction?
Lol, maybe I need to go out and buy me one, the only pedal I did try in front of the Axe FX Ultra was an overdrive pedal, and to me it was no better than within pure Fractal-space. It would be really cool to hear this elaborated on more.
The Hendrix blend of octave/fuzz was always something I couldn't fathom solely with the Fractal stuff I own.
