Great mic set up with the fx6

So far this mic setup has been great. The inky reason I first have 5 stars has nothing to do with the product, but I haven't used it in all types of settings so I don't know if it's easy to change frequencies if there is any interference. But the sound quality and ease with the fx6 are unbelievable.
