Well... It's a noise gate. It does what it says it does. With some caveats.
It works pretty good, but even at the slowest decay setting it can be a little slow to activate. There's 2 modes - mute and reduction.
Mute works by completely stopping the signal when treshold is reached, and reduce, just reduces the noise overall above a certain treshold. Both modes have their uses depending on what you need, but the decay on the mute setting is a little slow so i would not recommend it to someone who plays "djenty" riffs as it won't activate so quickly between the note rests.
For pretty much everything else, it's very usable. You do have to know what the controls do in order to utilize it properly (as with all gates) because it's not one of the "intelligent" gates. It works how you set it up. So if it doesn't work like you want it to, adjust the controls.
The quality is what you get from around $20 pedal. It's completely plastic, connectors are wonky at best and the on/off switch is really not suitable for freuqent stomping. You get what you pay for in this department. The knobs and the switches are ok though.
It has 2 ins and 2 outs so you can use the 4 cable method to even gate the preamp section of your amp through the FX loop. That's an amazing feature and it works well!
I recommend it to someone who either doesn't know if they need a noise gate or needs one that will stay firmly planted on the pedalboard and not stomped on too much because the stomp switch feels flimsy and will probably break with frequent use. Leave it on and forget about it, that's the best use of this pedal because it does the job, just won't stand up too much abuse.
