I just purchased a Dunlop DC-Brick in hopes of stopping the hum which I thought my older pedal board’s power supply was giving off. Would a better power supply such as the voodoo lab 2 solve this problem or is it the actual pedals which cause the problem?? I do notice an increase in hum when my compressor or/and overdrive are turned on.

Yeah, the Voodoo Lab Pedal Power is really, really great. I've never had any problems with it causing extra noise and such, in fact each output is isolated, so a lot of other issues are resolved as well. Just follow the instructions and call Voodoo w/ any questions (a lot of times the pedal makers are also able to give valuable input as well) and you'll have very few issues, if you have any at all.

Have you tried a separate wall wart for just the problem pedals while leaving the others plugged into the Brick? This could solve the problem. My Brick is dead quiet.

effects pedals are noisy and there is no way to stop it unless you redesign the pedal. you may find a pedal that is quieter, but in general effects pedals are poorly designed. try the pedals one at a time and reject the noisy ones. There is no gadget that will make a crap pedal into a good one, sorry.

The problem could also be in the wiring of the building that you are plugging your supply into.

I would suspect a boost, of any sort, might amplify line noise.

Do you hear this noise when running pedals off of batteries or just a transformer?

Any Hum what cranking up the amp with the guitar plugged into it?
Is the hum being picked up by single coil pickups? Would the hum go away when the volume pot is on your guitar is turned down?

Just trying to trace the source of hum.
Are we sure that it is the power supply?
Have we gotten this hum in multiply locations or just one room?

the problem starts with the pickups, not the building. I have been through this a million times. All pickups will pick up 60 cycle noise from the amplifier itself. That 60 cycle is reamplified by the pedals and the amp, the more gain the pedals and the amp have, the more noise comes out in the end.
If you start with the best humbucking pickup like a Gibson or EMG you will amplify less noise. If you start with a single coil pickup, you are crap out of luck.
No, there is no way to shield a single coil pickup with foil or otherwise, you are wasting your money.
Power supplies for pedals are very poorly designed and have lots of 60 cycle hum. that hum is again re amplified by the pedals and the amp.
If the signal chain, power supply is redesigned the hum can be reduced dramatically, but that is not available off the shelf. There is no easy solution that is "plug in".
this is because manufacturers have paid such poor attention to noise in pickups, amps, pedals. It's a design issue. You can rewire the building all you want, buy all the noise gate pedals on earth, and you will still have the problem.
