I'm looking to simplify my pedalboard connections to relieve my OCD for stage clutter. I've always hated the idea of having separate cables for send and return to the effects loop, so I was thinking of combining them in a box to a stereo TRS cable and breaking again at the amp. If I had the send and return share a common ground, would I be getting noise from ground loop or whatever? What if I went further and used a 4 pin XLR so I can include the instrument send, with common ground? I remember reading that people have noise problems if they share power supply between effects loop and front end effects.
Thanks
