hey guys

all of my ehx power supplys are hissing and humming when in every single power route in my house

this noise is coming up though my amp
its not a grounding problem cause i have tried it at several different houses miles apart

what could this be ??
could it just be that there not working properly ?
or am i overloading the extentsion cables, but still if i was why arethe doing it when singly plugged into the wall ???

also after several threads and severl differt forums im still having problems with my effects loop

my 1echo pops when turned on and it also gives this squelch sound too, thus even when playing and turning on the effect it still happens, when i have my holy grail reverb in the loop it does the same, also my SEM does this too

i have had many problems with my loop
few people said it was the tubes gone in my effects loop but my effects loop doesnt have tubes
all the cables are good ones

when i first got the amp i had no problems but over the last few weeks its been a nightmare

all of my ehx effects are not daisy chained they are all using there power supply given when purchased

some of my other pedals are but they have never gave me problems and they are not in my effects loop, they are in he front of my amp

i just feel like im not getting anywhere with this problem

your help will be greatl appriciated

thanks
