Limiter for feedback

[jlawrence2158]

Hi I own a Marshall half-stack and HX Effects. I like to set the amp volume very loud to get the best distortion,

then use the HX Effects to lower the volume in db in the signal chain after FX loop using the Noise Gate/Hard Gate as last effect

to match whatever level I actually need for band, home etc. 

 

The problem is I'd like to avoid the feedback that occurs when the noise gate is disabled to change a channel, make edits, accidents, etc. 
Its very rare, but when it does the amp is super loud with potentially damaging feedback, want to protect my speakers even in rare cases. 
 

Does anybody know of good way to avoid feedback , besides the obvious answer of "standway from the amp", "lower the volume"? 

A rackmount limiter or feedback suppressor is my thought, but they all seem to have TRS or XLR outputs. 

 

Another problem, when I change channels through HX effects it changes the scene first, so going from a dirty channel snapshot

with gate enabled, to snapshot clean channel with gate disabled, has feedback effect also, because the scene change happens first

with dirty channel on, gate, change snap,  no gate, feedback, send channel change,  (too late to avoid it), then after the channel change cmd

is received everything is fine.

Have you tried setting up the gate on your clean channels with a higher threshold(you can assign the 'Threshold' parameter to a snapshot)? Not enough to choke the sustain but maybe just enough to prevent the momentary problem you are having. Also, are you using instant commands with your snapshots to change channels on your amp? From your description of your setup it sounds like you have it right. An external noise gate might be your best bet. Maybe someone else will have a more creative solution that keeps the gate engaged while you change the channel on your amp.
