    Aaaaand the mandatory color coding so band mates don't have to wait for 30 minutes while I trace cables trying to remember how I had wired it up again [emoji28]

    DIY patch bay ground noise

    The pics I posted above obviously are from my small board and that is only used to run to the Fx loop.
    On my Splawn board I have a 6 outlet junction box that runs to the Fx loop, front of amp and handles the cables for channel switching.
    I have zero additional noise in my signal from either junction box.
    I would think a properly isolated and ground box wouldnít add noise. If you are getting some itís likely something in the wiring/grounding.
    But, Iím no expert. Thatís why I had someone else build them for me. Lol

    Well I started drilling the box now. Won't be able to finish tonight but will hopefully have something put together by tomorrow evening. Fingers crossed!

    That is probably the best of both worlds, but you still need a metal box, the reasoning behind that is the grounded metal jack grounds the box, creating a shield around the isolated connections.

    FWIW, I have had noise issues from sharing a power supply on pedals in front of the amp and pedals in the loop, the solution was to use separate power supplies or different outputs on a brick with truly isolated supplies for fx in front and in the loop. Not sure what would happen with the NS-2, I wasn't using one then. (FWIW that is one of my favorite noise suppressors)
    Currently, I've had no issues with noise in my setup. I'm just not sure if having all cables connected trough the one patch pay, as opposed to my previous setup with three 5 meter cables running to and from the amp will be a problem. What's really making me confused is a lot of sources say different things regarding the need for using isolated or non-isolated jacks.

    Stinkfoot, for instance, recommends using one properly grounded jack and then isolated plastic ones for the rest of the box.

    A metal box will provide some shielding and also ground the "grounds" (rings) together, which is probably what you want. OP, what exactly are you using this patch bay for?
    The idea is to run cables from pedal board to front of amp, then FX loop to and back from pedal board.

    Im just trying to figure out if I'll have any issues with ground loops. Esp seeing as how my NS2 is connected in X pattern, so it's already both in front of and in the loop.

    Ok, so this is just a box for running to my Fx loop. 2 ins and 2 outs. Hopefully youíre able to see what you need.
    Itís metal enclosure.
