Yes I could, but I also use them in front of amps... some of which have not FX loops. To me they sound excellent the way I am using them... in front of amps. And Simon has said that, although they have been designed to be used as primary pre amps, going into power amps, that they also can be used in front of amps. I am thinking that I am not the only person using them this way. I am just trying to see if anyone else is using them in front of their amp AND how they are dealing with the input volume situation.
