Help with connecting a noise suppressor in amp’s effects loop, 4CM

[cdtreadwell429]

Hello, hoping someone can give me a little guidance.

 

I connect my Helix LT with my EVH 5150 III 50W in 4CM. I’m running into some excessive feedback issues on the red channel if I raise the gain over 2.5 (just below 9:00). I’m trying to utilize a Boss NS-2 noise suppressor but I need a little help with the proper hookup. I want to place it after the EVH preamp, in the amp’s effects loop, before the time based effects of my Helix LT. I would think that just putting it between the send of the EVH and the return of the Helix would work, is that right? Would I just go from the amp send to the input of the NS-2 and from the output of the NS-2 to the return of the Helix? Could someone give me a layout of the signal chain, please?

I think this is the optimal cabling:

 

guitar -> NS-2 input

NS-2 send -> Helix input

Helix send -> amp Input

amp send -> NS-2 return

NS-2 out -> Helix return

Helix out -> amp return

Thank you for the insight. In an effort to reduce cables, is it possible to eliminate going into the NS-2 before the Helix and just from the amp send to the NS-2 input? And NS-2 output to Helix return? So it would look like this:

 

guitar -> Helix input

Helix send -> amp Input

amp send -> NS-2 input

NS-2 out -> Helix return

Helix out -> amp return

How does that reduce cables? Don’t you need cables into and out of the NS-2 no matter where it sits in the chain? Try it both ways and find out which sound/tone you prefer.

It's possible and works, but:

The advantage of the NS-2 is it's loop that allows for signal detection with the clean guitar signal but gating after the overdrive/distortion inserted the loop (the amp's preamp in your case). Your proposition wouldn't use that advantage and you could skip using the NS-2 altogether and use a Helix Noise Gate block after the FX loop block instead.
