my ehx knockout equaliser is creating loads of humm through my amp, what could this be?

I would suggest a noise gate, but that's not what you need in your case.

Just try cleaning up your power supply. Think about investing ino a power conditioner. These things are a life saver as well as cleaning out the "gremlin's" in your power supply.

the same power supply is also powering a behringer pedal tuner, but the pedal still hums when the power supply is only powering the EQ

I'm sure you have tried it but...

Is the hum still present when you plug directly from Guitar>Amp?

Have you done that with both your instrument cables? Trying each one?

Sorry, I'm kinda detailed about this stuff.

I wouldn't cheap out on a noise gate, there can be a pretty drastic difference in a cheap-o and good one.

I've personally never tried the Behringer, but just to be on the safe side, I'd suggest you go with a used Boss NS-2. Last I checked, they're ~$50 (~37 EUR) on eBay. There's a bit of a price difference, but I can say from experience the Boss is good quality.

If budget isn't a concern, though, get an ISP Decimator (~$100 or ~75 EUR). They're the best suppressors that I've ever used.
