I actually stopped using zuuls. I have a decimator x g-string. And while it has to be turned up way more to kill same noise as the zuul, it has completely natural sustain and decay.
With it run in 4cm and in loop, i put a regular decimator x before the amp with a cable link for tracking and it controls my clamp.
The two zuul method is very powerful and i used to use it a long time ago. I think that may be the fastest gating i have ever used. But what i have going now with the sustain fits my playing better.
