Decimator Ups the Ante

ISP's Decimator II guitar pedal ups the ante over the original Decimator design to give you even better noise reduction. An 1/8 phone cord lets two pedals directly track your axe, delivering amazing tracking performance. You can use one block of Decimator between your guitar and amp and a second in your effects loop. Decimator II sports linearized Time Vector Processing in its expander tracking, giving you incredibly smooth sustained-note decay that's virtually free of release rippling. For the ultimate in electric guitar noise reduction, put an ISP Decimator II in your signal chain.

Aptly named

I had a hum in my EVH 5150 50 watt head. The girls at church were complaining. Of course you could not hear the hum when I was playing. You could only hear it when the music stopped. Nevertheless the sisters complained, "he's to loud and to aggressive". The pastor laughs and says, "It's called a amplifier". Lol. To keep the peace, I called Sweetwater to help. They asked what my setup was and told me I needed the ISP decimator and where to put it in my chain. Unbelieveable!!! The hum is gone. In fact, it's so quiet that I keep checking to see if my volumes up before each song and checking my tuner to see if it's on mute mode. With the guitar volume on 10 and on the burn channel of the EVH there is no noise! Complete silence. I don't know who I love more right now, the guys at ISP for the decimator or Sweetwater for their continual willingness to explain, help and put the right equipment in my hands. One thing is sure. I can now crank the PRS Tremonti through the EVH 5150 50 watt and make a loud joyful noise to The Lord, as commanded in Psalm 150, and as long as the decimator continues to due its job, keeping everything quiet, the sisters can't complain. I just realized something, the decimator keeps the girls quiet also. Thats a 2 for 1 special. Lol. Seriously, Great product ISP and great recommendation Sweetwater. I love it.

Just buy one already!

It's a noise gate. You need one. But really, this noise gate should be simulated by every digital guitar processor and amp simulator out there! It's easy to use, doesn't fail, and cuts clean! What more could you need? Works great live! I've found myself wishing for a simulated plugin of this gate to use in Protools (instead of bussing tracks out). Just make sure that if you're running it with batteries instead of a power supply, you'll need to unplug any cables after each use, otherwise you'll be going through batteries like they're going out of style!

It's Majic

I don't know what it does or how it does it, but this pedal really cleans up the signal. It makes all of my guitars sound awesome. I wouldn't say it's completely transparent, but It cleans up your signal in a good way. Single notes pop off the fretboard. It gets rid of the muddiness. It's much improved over the first generation decimator. I even convinced my band mate by A/Bing it against the first generation pedal. He put his old decimator on eBay and ordered the decimator II right then. You should give it a try.

This could silence an earthquake!

I have tested the Boss and MXR noise gates/clamps and this pedal did an amazing job of cutting out unwanted noise without touching the sound. I ran 5 different OD/distortion pedals through this bad boy at the same time - the Decimator 2 could be adjusted to cancel out every bit of the hiss, buzz, and squeals (of course you would never run this much gain, I wanted to see how far I could push this pedal). With significant gain, you can set the threshold relatively low and cut out the noise, but keep the great sound without any clipping. I do a lot of home recording as well as club playing and wanted a way to cut out hiss for recordings, as well as feedback when I crank my JCM 800 for shows. This pedal works great in both settings. Word of advice - when you are using heavy gain and have the threshold setting a little higher, but then you back the gain down, you may want to adjust the threshold to compensate the lower gain. In other worlds, if you have your threshold set too high (too high for the amount of gain you are using), you will notice the performance of your sound drop a bit. A simple fix, just drop the threshold down a bit. Finding that perfect setting is very simple. This pedal is the way to go.

ISP Decimator II

ISP Decimator works great! It really cleaned up my pedal board. I figured out you have to keep it pulled back a touch or it can cut out long sustained notes. That said, it was easy to fix by turning the knob back a touch counter-clockwise. Great pedal!! If you play with people or sound guys that comment on hiss, get this thing! Well worth the money. Also- I noticed very little, if any tone loss... and I am hyper-sensitive to tone loss.
