another Smothie question

[scotheath]

I'm playing my new build through a mesa combo. the amp has a little hum to it with no signal, (when not playing strings muted)  which it always has, but now when I switch on the smoothie pedal the hum has the rise and fall of the pedal. is that normal or is there maybe a ground issue?

What about with no guitar plugged in?

same thing, unplugged cable into amp, rise and fall. pedal off just hums

And just a buzz with nothing plugged in to the amp? It could be anything from the wiring in the house to things plugged in and around the amp to an electrical issue in the amp. Does it happen all the time no matter where it's plugged in?

sorry I should have mentioned that it was on the distortion channel. I've found that on the clean channel the rise and fall off the effect is still there but at volume greater than half. I turned on my donner flanger and found that it does the same thing at loud volume. so I guess maybe that's normal, and that on the dirty channel its more obvious at lower volume. sorry to waste your time but thank you for the help
