Hi,
I used those and got the very same results too. Most Bos pedals use tend to 
use adapters that are 200ma, and anything higher introduces unwanted noise, 
and there are two different ones for their pedals, and most of the digital 
pedals, like their digital delay and reverb pedals us the PSA120. Peavey 
used to have a terrific reverb pedal that you had to use an adapter as it 
wouldn't run on batteries, and it was a 200ma, but different than the ones 
Boss used, and when anything else but the adapter that was used that wasn't 
called for, it was so noisy that it was completely useless. However, there 
are better quality power supplies made by Guyatone (under the name Godlyke) 
and some other companies that will properly power anything with the correct 
adapters and will automatically adjust to the MA rating required to work 
correctly, and I use one made by Guyatone and have never had a problem with 
it, and it powers my Guyatone delay and reverb pedals as well as my Nady 
wireless unit winout ANY problems. Those things from Radio Shack just ain't 
worth a damn for anything.
