Hello, new here. I would like to know if anybody has tried using a mixer in the effect loop of their guitar amp. My guitar amp only has a serie effect loop and sometimes, I would like to be able to vary the ratio of dry sound/effect sound past the preamp section of the amp. I would like to split the preamp output into two channels of a mixer, balance each to my taste, and send the mixed output to the power amp stage. Will I run into problems? I do not own or has access to a mixer, so I'll buy one if there is a reasonable chance this would work.
