Okay, thanx.
I wanna use it for bassguitar.
Had the BassPod XT Pro and the Ampeg model was great when cranked. But I wanna have a clean low end. The X3Pro and HDPro can run 2 amps at once, so the idea was to run 1 clean amp, just use the low end, and run the second distorted amp without any bass. And then mix it to a mono signal straight to the PA and my bassamp.
