Title: Darkside extreme hum prob
Post by: G.G. on June 12, 2011, 08:44:39 PM
Hi Folks,
I got my Darkside wired up and in an effort to "rock before I box" I have it taped down on a cutting board while I plugged in to try it out.  It seems like everything is working correctly except I'm getting a really, really loud hum over top of everything.  It sounds like some kind of a grounding issue, would that most likely go away once I got it all into an enclosure or do I need to trouble-shoot some more?  The pedal sounds good, except for the hum  :-\

thanks,
Gray

Hi i think SLEEVES from the jacks and Circuit grounding will affect after all of the grounds go on the box (enclosure) to a general GROUND as you can see output SLEEVE dont be at all connected to ground in the schematics before boxed ,try to ground S9-input sleeve-output sleeve with crocodile wires and see if the problem is fixed.
