Ok really really annoying problem, I have a Marshall MG100DFX with a variety of guitars from strats to les pauls. When i play my guitar through my amp direct with no effects or anything wired in its absolutely fine. However i have a pedal board with the following pedals on it: Cry Baby Wah Pedal, DOD Tech 4 effects processor, Boss Super Chorus and a Distortion Pedal. The board is powered by a 9V DC brick so all the pedals are powered off one power supply. Now when i plug this pedal board in no matter what order the pedals are in it, i get a hum from my amp.
I ahve tried a variety of things to get rid of it. I have eliminated the DC brick and run everything off battery power. I have taken each pedal out the loop and tried without it and tried it on its own and no matter what pedal goes between the amp and the guitar, even if it is only one, it still hums. Obviously without the power being from mains it cant be an earth hum. I have powered the amp and floorboard off one socket and stil have the problem. It seems that no matter wot i do its still there.
DOes anyone have absolutely any idea of how this could be sorted?
Many Thanks

I wonder if putting a noise gate in the loop would help.

Sounds like it's time to check the amp. Does it hum with only a guitar, no effects? And does the guitar hum through another amp? Actually, have you been able to try this out with a different amp, or even more difficult, can you take the entire set up so another location? It sounds to me like you've tried everything else I would think of already.

firstly any make/model of a good noise gate wud be great, i was at a band practice for a function band and had the hum last nite and tried to sort it out there too and failed, so its not a power problem and ive also tried thru my bro's amp and its still got a hum. It hums with the effects but no hum when the guitar goes thru the amp alone.
effects can be noisy. when linkied in a chain they get noisier. maybe an effect is part way broken?
patch cords going bad?
