I have a Bugera 333 Infinium head, and run my pedals as follows
Boss TU-2 -Morley Bad horsie - Biyang x Drive - Front of amp
Biyang Aqua chours - Digitech Delay - Behringer noise suppressor - into fx loop
I power my pedals using the Harley Benton power plant, and on the clean channel of my amp it works normally, but as soon as i go on the crunch/lead channels i get a loud horrible sounding Buzz/Hum that even my noise suppressor won't cure.
After this i tested every pedal with the power plant separately and still i got the same noise.
after this i tried all my pedals through the amp with batteries and everything sounded normal, so my first thought was the power plant was faulty.
the other day i decided to buy a plug/daisy chain to replace the power plant, and when it came i wired up all my pedals again, and too my dissapointment the horrible noise was still there! so then i thought it has to be the mains i am running off so i tried different plug sockets all over the house and nothing changed, i even took my gear to my next door neighbors house and still the buzz was there.
I have tried to find out what is causing my problem, but i am just stuck on what to do, i have read up i need an 'isolated' power supply, but i don't want to keep throwing away my money.
I anyone has had similar problems or could help me with my issue i would really appreciate it
