TC ElectronicSENTRY NOISE GATE Multiband Noise-Gating Pedal with Hard-Gate Mode and Built-In TonePrints*

TC Electronic never disappoints. This pedal is a quality investment that, if used properly, will remove the noise due to pedals from your signal chain 100% of the time. It'll also take care of any noisy cables you put inside of its loop, but you should check for and resolve any issues with noisy cables in your rig before buying a noise gate. To use this pedal, wire your noisy pedals (typically distortion/overdrive/fuzz) into its send/return loop, use the dip switch to select your gate, and fine tune with the knobs. It took me less than a minute to dial in; here are my settings: 'Hiss' mode, "Threshold" at 10 o'clock, "Damp" at 1 o'clock, and "Decay" maxed out.A note about the available gates: 'Gate' is a digital noise gate modeled to behave like a traditional noise gate - Think ISP decimator. You will hear the pedal's gate when it engages in this mode, but you're supposed to. It's great for heavy metal/djent. 'Hiss' is TC's proprietary multi-band noise gate, capable of removing low-frequency noise (60 cycle hum from your pickups) and high-frequency noise (pedal hiss) from your signal at the same time. You won't hear the gate shutting in this mode, either - It's transparent yet extremely effective. It's really quite magical. No matter which mode you've dialed in, when the gate is off or the pedal is disengaged, the pedal will not color your tone at all thanks to TC's true bypass. No cheap Chinese buffer circuits here.However, the feature that puts this pedal a level of quality above the rest is TC's TonePrint. Let's say 'Gate' or 'Hiss' are not doing the trick for you. Perhaps you want a multi-band gate like 'Hiss' with a hard shut like 'Gate'. Maybe you can't find your gate's sweet spot without sacrificing your guitar's sustain. Or maybe you just cannot find the sweet spot at all. With TonePrint, you have access to a significant amount of parameters inside the pedal, beyond the 3 knobs on top. The options are quite limitless and will allow you customize the perfect noise gate for your rig.TL;DR: Have you removed all cable noise from your pedalboard, yet are still stuck with annoying hiss when you aren't playing? BUY THIS PEDAL.

Great noise gate. Very responsive. I have used in 4 cable method and it responds really good.

I use the pedal in the 4 cable method. The amp is completely silent. I leave the effects loop on and have a loop switch pedal to bring pedals in and out of the effects loop marshal DSL 20HR. I own an amazon noisegate, it broke, and a boss ns-2. The boss works but doesn't do the metal thrash gating. This pedal is incredible.

If it wasn't for the jumpy encoders in the Windows toneprint software and the (currently, 2018-12) missing manual on the tc electronic website I wouldn't have hesitated to give this pedal 5/5 stars.Long story short - the pedal is by far the best thing that I could have added to my guitar chain and after some tweaking it converts any noisy high-gain amp and pedals into something controllable that is fun to play with. I wired my pedals and preamp into the send/return loop so most of the presets in toneprint may be too aggressive and it is worth spending an hour or two playing with the parameters until the pedal reacts as required. The result I got makes the SENTRY react as if it wasn't really there. No pumping, hissing or cut-offs left. My guitar rack now just feels like I would be playing with a super modern, extremely quiet metal amp. The hiss of my overdrive pedal and the quite noisy Engl E530 preamp are gone. However, even subtle hammerings on the fretboard are audible and ring out naturally. I haven't used the mac nor the iPhone & Android interfaces.Cons:- tc electronic using toneprint as one of their main selling arguments for their pedal range and not offering a user manual is a no-go. I think I am not alone when I say that it is not really self-explanatory why things react like they do in the interface. A basic 1 or 2-pager should be the minimum- 'encoders' in the Windows interface are very 'jumpy' and it is hard to dial in the desired value. Adding the value with the keyboard doesn't work either. That would be a nice thing to add/change in future versions (current version: 4.05)Pros:+ Everything else. Still amazing value for money and absolutely recommendable

OK, I often search for a lower priced Chinese equivalent to save money on pedals, but they didn't have an equivalent and this had good reviews. I turned this on and it worked perfect! I thought something was wrong it worked so well - I clicked it off and there was the original loud hum!Realize this has a send/return loop which is why I got it, and if you want to cut out noise, this is the only way to do it. You need this up front to sense your raw signal and then use that to gate off the end of your effects chain. But typically, you want things like echo and reverb after this so when it shuts off, you hear a very nice trail off with the echo/reverb. Just dial it so it kicks on quick and dial it down so when you're at the point of no signal, it shuts off the back end (hiding the amplified noise from your other affects).I use a compressor, sometimes when I'm doing distorted leads and sometimes while playing slide. I first had the compressor right after this, but then I found I was missing the tail end and it cut off too soon (that is, my compressor was raising the level, but the noise gate didn't know that). So I put the compressor before this and all was good again. The compressor would hold my raw signal level high, the gate would remain open, and when the note totally faded away, the gate kicked in. I can do Strat single coils into compressor into super distortion with other affects and you'd never no it. Click it off and year that old awful hum. Now, silent bliss. Very cool and glad I paid a little extra for this.

Great noise gate

I don't have a lot to say other than this pedal works great.
