Hi guys, I've just received my brand new axe fx 2 today and i've been trying to dial in the tone of my mark v head mainly the mark 4 channel which im having a hard time doing, im running the axe in to a matrix gt 1000fx poweramp in to a mesa rectifier cab, im a bit confused by the advise in the manual that says to turn off the cabinet modeling when running in to a guitar cab but when i do the amps sound really thin and harsh. im confused if im running the right settings or not, there are so many variables to figure out with the settings it's really confusing, hope you axe experts can help! thanks
