Noise gate question

[MGW]

I got a Soldano X88R clone and I'd like to integrate a simple noise gate circuit into the lead channel. I've looked around the web but haven't come up with much. Any thoughts?

Try this. You can also parallel in a 1MB pot with the switch to control the amount of squelch.

That's exactly what I was looking for. Thanks!

Where in the circuit would this go?

aha! Gracias!

Thanks for the JSX schematic. Great example of the implementation of this.

Has anyone tried this yet? Seems too simple to be true... Hoping for the best though, great timing got those diodes on an order I just put through so I'll absolutely be giving it a whirl!

Any more simplish design ideas out there perhaps?

I threw it in after the third stage in my X88R. Brought the noise down dramatically...REALLY DRAMATICALLY. I can't tell any difference in the tone untill I roll the volume WAY back...but who does that with that much gain. And, the tone doesn't necessarily change, you can just hear the "gate" closing. I do wonder if it is possible to change the speed of the gate. I did put a 1M pot across it, but it seems that is just letting signal bypass to some extent as the noise floor was raised a bit when I did that. All in all, it's a win in something with that much hiss.
