Simple Noise Gate?

[Dylan]

So as some of you may know, I've really gotten into building guitar pedals lately. The biggest problem is a few of my pedals have some nasty buzzing when they're engaged. I've searched for a simple noise gate schematic but all I really found was VST's which I don't need. Does any one know of any simple schematics for one? I was thinking of messing around with some switching transistors, but if I can find something easy to build I'll just use that.
