I'm re-writing my rack with a new RJM effects gizmo,
I decided to do some individual loop testing to make sure where was no problems before bolting it all in place and finding a problem.
When I plugged the guitar into the front input on the effects gizmo there is just a terrible loud buzz so loud you can't actually here the guitar, it's like a very faint noise I the background.
If I plug it into "input 1-4" in the back the unit works fine, clear sound and the loops are working, so I'm confident no problem with any of the cables in the gizmo loops or the cable to the amp (obviously done the stand alone testing of cables etc too)
What would cause the front intput to be totally unusable, but the back "input 1 - 4" to work fine, is it likely to be something like a loose cable on the front jack inside - or more likely to be my wiring configuration, I only ask as I don't want to take the lid of this thing to even look unless I have to.
