I have a Samson Wireless that I run from a sm57 into my harp rig. I've got the signal cranked to just below clipping, but I notice a volume/gain loss when comparing to a cable. Would something like the MXR ten band eq work for bumping up the gain/volume of my mic signal? Anything simpler/cheaper that'd do the same thing. Really, I just want to make my signal a little hotter. The eq part isn't an issue. Thanks!
