I play through a modeler only.
The PA rig is mine and all the monitor gear is mine.
I love it, live in stereo my delays and other effects sound great.My floor monitor in front of me is cranked so I get feedback from my guitar just like I would my 4x12's and power amps, but I only have the weght of a 2 space rack to lug around.
Our audience members that have been around us for awhile say that the FOH has never sounded better,balanced ,clearer, cleaner.
Theres alot to be said for modelers used live from a sound guys point of view.
It was just another learning curve and adjustment to get used too, but now I prefer to go this route, AND the owners keep on booking us!
