How much does power supply affect noise in your chain, and what are the best remedies, particularly with wal-warts?
Was experimenting this AM with my chain, which currently goes bunch of dirt/ods/ -> UD Stomp -> Vox DelayLab -> Jam Man Stereo. I've had suspicions about the UD and noise before, and a little with the delay lab. I pulled both out of chain and there was pretty significant white noise difference. Then I pulled out my LS-2 and put the UD in the loop and experimented. Indeed a higher noise floor with it in the chain. I guess it'd be considered hiss? Sounded like a faint version of the white-noise they pump in at work to me. Did the same with the DelayLab... same result.
Is it a delay thing? Is it because they use wall wart supplies (guess i should try batteries on the DelayLab).
If I had the wall warts going into some type of power condition would that help? Recommendations?
The other pedals are using a one spot just plugged into a typical 6-outlet power strip. Both wal-warts are in that strip as well. Amp is on a different outlet.
