I have looked at the Quad Cortex and it has some nice features. I very seldom use two amps. The FM3 is miles ahead on effects and tone.
Cliff is a very smart man. Helix came out with a nicer interface to change patches. Cliff countered with the FC6, and FC12.
Now Quad Cortex has created a killer touch screen interface with a huge amount of power with a lot of switches for changing scenes and patches. I think most of FM 3 and Axe FX user already have an FC6 or FC12. I think the cost would be too great to have and AXE 3 floor unit with 12 switches.
This is just speculation on my part, but I see a three switch new unit, let's say FM4, coming that is actually the same or more powerful than the Axe 3. Touch screen and rotary encoders are very nice but what is the cost for that? The casing for the Quad Cortex is very thin. I had to reseat one of my ribbon on my motherboard on my Axe FX. When I opened up the unit, I was so impressed with the quality.
I am a player that likes very few big presets. I like it to never have to bank up or down and to be able to use 10 presets and 8 scenes each.
It would make my day to have a floor unit that matches power wise with the Axe 3 or more power.
My friends we have it all. Really the only thing needed is bigger processors for the next generation floor models.
Helix hardly ever has an update. I don't know how often Quad Cortex will update, but no one is a relentless as Cliff at making things better while maintaining cost getting out of hand. You have to also have to be a good business man. Well could all add to the list of wants to make a unit cost $4000. We don't want that.
