This may be a shot in the dark, but has anyone had good results using this as a live, effects-only unit? I don't want to use the amp/cab sims, just the effects in a couple of tunes. Would one just turn off the amp/cab simulators, then tweak the effects to taste? Could it be that easy? I realize that it will probably not be the best sounding thing I could use. Just curious if anyone has done this, and how they did it. Thanks!
