"Ralph this amp has no pre amp, no pre amp stage so there is no fx loop as there is no pre amp stage to put fx behind or in front. \n  \nMy Mesa dual rec does have a pre amp stage and a amp stage, so I could use the 4cm with helix. But I'm pretty much happy with Mesa dual rec how it is. \n  \nMy powered monitors are doing well with helix \n"
