Description
ISP Technologies Decimator ProRack G Noise Reduction System
ISP Technologies Decimator ProRack G Noise Reduction System is the ultimate solution for those who crave a noise-free, clean signal path for their guitar. Tired of the unwanted feedback or noise creeping into your performance during pauses or when aiming for percussive riffs with clear breaks? The Decimator ProRack G is your saviour. This system offers a twofold noise reduction system that handles noise like a pro.
The first channel feeds directly into your pedalboard or amplifier, eliminating noise before it even hits your gear. The second channel is designed to reside within your amplifier's effects loop, killing any hiss and thermal noise created by the preamp. This provides a clean, noise-free sound, allowing you to enjoy razor-edged stops even with massive gain without losing any tone quality.
With the Decimator ProRack G, you can now get all the gain your amp can handle without worrying about noise or feedback. This is a must-have gear for percussive, aggressive rock and metal styles, including djent playing techniques.
Key Features:
- Ultimate solution for noise and feedback reduction
- Twofold noise reduction system for efficient noise handling
- Channel one removes noise from the signal before it hits your gear
- Channel two eliminates hiss and thermal noise created by the preamp
- Threshold controls for each channel for sensitivity and overall noise reduction strength
- Perfect for aggressive rock and metal styles
- No change in the guitar tones for authentic sound
- Easy handling and usage for best sound results.

Got a tube amp, a boost/overdrive and a terrible amount of hiss? STOP COMPROMISING AND GET THIS!
Let's face it, we all love the high-gain tones. And at the same time, we all despise the all-too-familiar extraneous hiss.
Personally, for a long period of time I was constantly getting disappointed by how pedal-based noise gates weren't cutting it enough. The Boss NS-2 sucks up tone, the TC Sentry leaves you with a distasteful digital signal, a single G-String eats up sustain and the two Decimator II's in a link system eat up pedalboard space, not to mention a potential for cable short-circuiting hazard caused by a TRS aux cable that's needed to get the link system working.
That was, until I finally ran into this. The ISP Decimator ProRack G. It's a two-channel noise gate that allows you to pick between instrument level and line level. Not only is it very versatile in terms of setup, the Filter Tracking also allows you to hone in on the refined clamping of the noise reduction. How does it sound? Very transparent - even with a 1st Generation ProRack G I have, the rack unit does a fantastic job at clamping the unwanted high-gain noise while keeping my signal as clean as it could be. What can I say? It gets the job done without any nonsense.
The only thing I would wish for it to have would be a MIDI input that would allow me to bypass the noise gate when playing clean tones, but even with it on, the clean tones are crystal clear.
Final verdict? Well, if you're a metal player using a high-gain tube amp and a boost/overdrive, and you don't like the extraneous hiss that's coming from your amp, stop wasting your time with other noise gates and get this rack unit. It's the be all, end all of noise gates that YOUR tube amp needs.

nah, I don't like really high gain tones... a stock JCM800 ahs plenty for me... with a soldano I never turn the lead channel past 5 on the gain knob.

"Purgason keeps his signal chain pretty straightforward, as well. After running through a Sennheiser ew 572 G3 wireless unit, his guitar signal hits a Peterson Stomp Classic strobe tuner (even aliens need to tune), before going into a Stereo Mod version of an ISP Technologies Decimator ProRack G," states Premier Guitar.
