I can see your point. In fact, I tried multiple cables, different slots, direct to board, altering freqs on my patches, ensured no cell phone in the area, no fluorescent lighting, etc. Then, for kicks, I yanked ALL of my high-falootin' Vovox cables -- all tested in good repair --on a whim and swapped with my NOS ;-) xlr cables. Problem disappeared. My guess is that the high freqs that were coming through the fancy Vovox cables created a sensitivity issue with how the Verve projected the sound. Back to my old tired xlr cables, with none of the above problems.
