Thanks for the info. The Axe does sound like it can do a great job in the FX loop of an amp or with the 4cm. If i were going to build a pedalboard, let's take a Timeline or Timefactor which are $400 new, and that's just for a delay pedal. Timeline's are now selling for close to $500 on the used market. By the time you get a chorus box, reverb, a phaser, etc, the price goes up past the cost of an Axe-fx standard, and you have a cluttered board and you have to do the tap dance if everything isn't MIDI. Although, some guys, myself included, still like to reach down and twist a knob.
I do feel a bit of disconnect with MIDI and not being able to abjust by twisting a knob, but eliminating multiple cables and boxes also has advantages. AGH, I'm confused.

Like i said though, for $1500 it's a good buy for what you get. With the Axe out, does it make sense to drop money on something like a G-System when the Axe can do everything and more?
