I may ultimately do this, but my first goal with the Axe was to, as much as possible, to recreate my existing setups using this A/B rig centered around two Egnater heads, Eclipse, Lexicon G2 and Synth in a complex W/D/D/W system with parallel signal paths for guitar, FX, synth, and piezo. The main goal of these systems were to minimize my pedal dancing. Having two parallel paths where I can toggle between them with one button is really important in my band due to how much I pop back and forth between them. I have one switch set up as Latching and the other as momentary. Tune like the Dregs Cruise control would be much more difficult to pull off live because I have 4 different signal paths and need to pop back and forth between them at a pretty quick rate. Also, having a standardized routine where I am always physically on the same two buttons is critical. The programs come and go, but the A/B switches are always in the same place.

The Axe FX Ultra is so damn powerful, it lets me simulate the guitar amp and FX side of my big rig with very good results. It even gives me some new live tones I don't have with the ampers. So, it is basically replicating the work of over $12,000 of gear and over 500 lbs for $2,000 and 25 pounds. I am now beginning to dig into it further and find new ways of implementing it in my writing and production process.
