I think the fx in the gt6/8/pro are all totally useable for live situations.Cool, thanks for the link. I don't care about any of the amp sims, just the quality and use of effects and the other cool sounding functions like you described. Do the effects sound just like all the boss pedals or can you tell a difference?
As does katatonia.Doesn't Opeth still use one of the GT floor units for live fx?
I replaced my G-major with the GT-PRO, and i'm really satisfied with it. Ok this is not a Axe-Fx, but it fulfill all my fx-needs.
I mainly use it only for the effects with my Laboga Mr. Hector. I'm going to try it also with the 4 cable method, just to try out different patches with amp sims. Great unit. Check out also http://bossgtcentral.com/forum/ and http://forum.thestompbox.net/forumdisplay.php?f=19
Plus, you wouldn't have to run so many stupid cables to the front of the stage (just a MIDI cable!)
