Howdy, Has anyone had experience placing the receiver of Line 6 G50 (or any other receiver) directly on top of their bass head? If so, did you have any issues? I just upgraded from a cheaper Nady system to the Line 6. The Nady system didn't like it too well when I placed it on top the head. It sometimes whined like a nagging wife. Just wondering what to expect from the Line 6 on top of a Carcin BX1500 head.
