I was watching a concert on TV the today and was struck by something. The guitars and bass are all running wireless, but they all have their collection of effects pedals under their mic stands. My question is how is that normally done? Do they simply place the receiver for the wireless on the ground right by the ground and then run a cable back to the board...seems a bit odd. Do they have 2 sets of wireless? Is it folded back using a an aux feed to add the effects? I figure if anyone can get me a good answer it is here.
