Decimator G String Ups the Ante

ISP's Decimator II G String noise reduction pedal tracks the signal directly from your guitar, which lets you go from clean to high gain without changing the threshold. This improved design lets you connect the processing channel into your effects loop after your high-gain pedals or preamp. An 1/8" phone cord engages the linking function, letting you link two Decimators for two channels of noise reduction (or a cool stereo setup). If you want the ultimate in electric guitar noise reduction, Sweetwater's got it: ISP's Decimator II G String.

I can't thank my Professional Sales Engineer, Aaron Cieslikowski at Sweetwater enough for all the knowledge he has and the great advise on the best guitar equipment and accessories to purchase from Sweetwater Music. And I must say I have purchased quite a bit in almost three years and everything is "AMAAAZING" as this review tittle says!!! I Don't write reviews often due to the fact I tend to ramble on. So here it goes. If you want to hear what your guitar/bass should truly sound like ran thru different effects pedals you need the ISP Technologies Decimator II G String Noise Suppressor Pedal. This is a must have for any pedal board. It totally takes out any hiss or hum when hooked up correctly. It might be a little spendy but when you hear the difference you will say "AMAAAZING"!!! Just Buy It!! Thanks Again Aaron and Sweetwater! P.S. Have A Blessed Christmas Too!

The best decimator available!

I recommend the Decimator II G String to anyone who wants the best noise suppressor! Sweetwater has the best pricing and they are very reasonable. But it will sound even better if you have the Decimator II and the Decimator II G String hooked up together. Either way, the Decimator II G String noise suppressor gets rid of the humming or buzzing. It works best to put it at noon.

Performs noise gate function very well

Simple to operate, and very useful for shutting down background hiss/noise that can be annoying when you are not actually playing notes. I have noticed no negative impact on tone or dynamic response. I use the ISP in the effects loop path in my amp. Keep in mind that once you start to play, whatever noise was in the background comes back on and rides on top of your signal. This pedal is not a cure-all for every type of noise. Also, you don't need to route guitar-out back to your main signal path. I have an input buffer on my pedalboard and send a spare signal from there to the ISP, resulting in simpler cabling and a cleaner main signal path.

Great Noise Reduction Pedal

This pedal is unbelievable. I'll have my cry baby, overdrive, and delay pedal going - set the threshold at -20 db - absolute no noise. While I'm playing my guitar the sound from my amp is so crisp and clear. But I do have to say one thing that was NOT good - that was the manual - I actual had to go to the ISP wbsite and download the original Decimator G String Noise Suppressor because that manual actual shows you aBETTER picture of the connection configuration - the manual that comes with this actual doesn't show in details the proper connection configuration. But when you do have it connected properly - it's outstanding! I love it!!! Thanks ISP but you need to improve your manual's configuration for this pedal.

What noise?

This thing (if you hook it up properly and with clean power, unlike some of the complaining reviewers) will kill all your noise. You could have crazy amounts of hiss and buzz, as soon as you turn this puppy on it's all gone (when you're not playing). You'll have to twiddle the threshold a little to figure out what works best for your playing. I can use the Decimator G String II to play anything from clean leads, to Hendrix-style low-volume crunchy ballads to thrash metal all on my JVM (which is known for its noise) and it sounds amazing. Worth the money in my book! And of course, your Sweetwater sales engineer will take great care of you throughout the entire purchasing process!
