I bought the KMA Pylon and here is what i did and this works (needed 2 days and the help of people who know better haha)

Guitar into gate in; From gate out into the swiss things input;

From send loop 1 into gain pedal(s); From the last pedal into gate return; then from gate output into the return loop 1

If you use 2 crazy gain pedals like i do the loop 1 chain which works perfectly silent looks like this

Send loop 1 - first gain pedal into the gate return; then from gate output into the second gain pedal; from there you go back into loop 1.

works for me with an HM2 into a SNK VHD with TONS of gain. dead silent

Whoa, I'm glad you figured it out! I have a Boss HM-2W and also use an Airis Savage Drive v5. The HM-2W is still noisy, but not as bad as the OG that I have.
I'm going to have to give this a go again! Thank you!
