Muzzle key input causing noise

[Gbiggs1986]

Everything appears to be working on my muzzle except when I turn the pedal off I get a lot of noise( I’m not being funny I know this is a noise gate) it’s very noisy. When I disconnect the key input the noise goes away. When the pedal is engaged it works as it should and everything is dead quiet.

I pulled the key input from the enclosure and sure enough everything works key input no longer causing noise when I disengage pedal. So for some reason when I remove the ground from the key input the noise goes away.

You have a ground loop. You need an insulated jack for the Key and omit the Sleeve connection.

I don’t have the sleeve connected. I used a neutrik switch tip jack. Is this jack from tayda insulated? https://www.taydaelectronics.com/6-35mm-1-4-stereo-phone-jack.html

No, the metal sleeve of the jack is making the connection to ground via the enclosure whether you have it wired or not.

You need a jack with a plastic sleeve, something like this:

6.35mm 1/4" Stereo Insulated Unswitched Socket Jack Solder Lugs

The product description incorrectly calls it unswitched, but it is switched.

Thanks! I figured it was from the enclosure. I put some electrical tape on both sides and in the hole and it works just fine. I’m going to source a couple nylon washers instead of using a plastic jack.
