Two Syn-2's With Boss NS-2 Noise Suppressor In Loop

[NewEraOutlaws]

As the title states, I'm looking to hook up a Boss NS-2 with two Syn-2's with the suppressor in the loop. Just to knock down on the buzz from higher gain modules. Tried hooking it up and just no luck. Anyone got any good tips? I'm sure this is an easy fix just needs to be plugged in right with the proper guidance, thanks.

I have the G-String, with 4 connectors like the NS-2, and it goes both before the SYN and in the loop. So, I guess the NS-2 would be the same.
