In my experience it's not a necessity. With a gate in the loop you'll kill enough signal to keep noise barely audible when playing at bedroom volumes. And playing at stage volumes you're hopefully wearing hearing protection anyway, so whatever noise is left when the gate closes 5ou won't hear much of anyway.I'll try it in the loop.
Didn't work either in the loop or between amp and speaker. I wonder why noone makes one.
Like I said, the source of the noise is my ac power bank that I just got. It's a charge able battery pack with a regular ac outlet so I can run anything I want off of, including amps. The problem is that it doesn't have a real earth ground, only a chassis ground. So powered by the power bank, all of my amps are excessively noisy except for the 1/2 watt nano. The nano plugged into the power bank isn't any noisier than my twin plugged into the wall though, so no big deal. I ended up with a way better portable rig than a pos battery powered amp. Nano into 10" Mesa closed back. I still think it would be a cool innovation since plenty of amps are noisy.
Is there some reason you can't do both?
If you removed all of your sources of noise, why would you need to mask it at the end?

So what this battery pack ya got with ya would fall under UPS(uninterrupted power supply). Well there are various kinds of these, you will get hum with a basic one.What you really need to get rid of the obnoxious hum is a Pure Sine Wave UPS. Even if you had a noise gate designed to be used between a amp & speaker unit, it would not mask the hum when you played, it would be at a very audible level, unless the power supply is clean.
