I have been a cable to amp guy my whole life. I don't use effects or pedals other than a Sansamp and Boss tuner. My usual gig is on a postage stamp sized stage in bars and small to midsize clubs. Recently my singer has been on me to go wireless. He thinks cables clutter up the stage, are dangerous and are uncessary with all the inexpensive and high quality wireless systems that are available. I personally don't see the need and on top of that I know exactly nothing about wireless systems, how they affect sound, what is too expensive or which are considered good for my purposes. Any help?
