Even when I run some of them off a good wall wart by themselves they still make noise. I run everything off a OneSpot and I've been looking at getting a better power supply. I just saw the the post on that particular forum and just wanted some advice from those of you that are way smarter than me if the bigger cap would make any difference at all. I will do as you said on a couple of the high noise pedals and socket the cap and see if that does anything.
