Muzzle key input question

Sorry for the necrobump, I am not familiar with the key thing what does it do?
, or how to use it?,

I want to build this sadly the IC is getting EOL, saw there will be a new version with the soic chip
 
The key is like a sidechain input...

It allows you to control the gate with your clean guitar signal, but actually gate the signal later in the chain (after distortion pedals, or in your amps FX loop).

Sorry I don't understand it completely, I really appreciate the explanation

Proper way to use it is when running the gate through the effects loop. It requires that you split your signal. Most guys split it with a Boss tuner but I just use a regular splitter. Guitar into splitter. Output A from splitter into the key input of gate. Effects send from amp into muzzle input. Muzzle output to any time based effects such as chorus and delay then back into effects return or if running no time based effects, muzzle output to effects return. Output B from splitter you treat just like your front of amp signal into any distortions/boosts etc then into front of amp. This way you’re able to use a clean pure signal into the gate that’s not effected by your distortion/boosts. It gates later in the chain after your preamp. Less chance of it gating too early and cutting off your desired signal. You can leave it engaged all the time this way even when switching to your clean channel because your still using a clean in-effected signal. I’ll draw you a diagram when I get a chance and post it. This really is the way to go.
 
This way you’re not gating a distorted boosted signal, just the pure clean signal from the guitar. All the gating occurs after the preamp and before the power amp. Just make sure you run any time based effects after the muzzles output and into the fx return. This way you won’t prematurely cut off any trailing delay repeats etc. if you don’t run any time effects just go straight from the muzzle output back into the fix return.

I get it now, thank you so much I really appreciate it
 
The Key input connections are marked on the wiring diagram. (Tip / Switched Tip)

Oooooh! OK. Now I get it. I was thinking I had to solder a ground in there, but it’s the switching tip so I do just follow the visual pic instructions. Thx
