OVERVIEW

Designed for those who want the ultimate performance in a foot pedal.

The Decimator G String is a noise reduction pedal that delivers performance like that of the renowned ISP Decimator ProRackG. The Decimator G String provides a totally independent channel of sound reduction that can be inserted into a series effects loop or after a preamp section with the advantage of having the Decimator level detectors track the guitar signal directly.

With the G String pedal you can set the threshold and no matter what level of noise the Decimator will track perfectly without any side effects. And the amazing thing is that you can switch from high gain to your clean channel and never have to switch the Decimator G String off due to the threshold being set too high. It's simply transparent.

The noise reducing pedal has an input to connect a guitar directly and a buffered output signal to feed the front of a guitar rig directly while providing a separate audio channel of Decimator that can be inserted in the signal chain of any guitar rig. You can insert any other pedals between the output of the Decimator G String and the input of your guitar amplifier. This allows the Decimator G String pedal to remove any level of noise you may have even with overdrive pedals at the front end of the amp.


Decimate your noise problems, whatever they might be. Call or click now to order.

I have this set up on my pedal board for use with a few amps. This pedal has inputs for both the front of your amp and for the effects loop. You will need a few extra wires in order to use this pedal for both. I have used several other brands of noise gates including Rocktron and MXR and I am convinced ISP is the only brand that works without affecting your tone or sustain. It works better than any other noise gate I have used (Not sure if technically the ISP is a noise gate, but it is a noise killer). The only possible drawback is that you may need to place the G String in a location that allows you to plug into the guitar input but also have wires going from the effects loop input/outputs so that they can be utilized. I had to re-arrange my pedal board a little to do this. Basically, what it does is takes away any unwanted feedback and noise from the front of the amp but also takes away the hiss and other noise by also running it through the effects loop. If you want your high gain amp to be virtually silent, you must also have a gate in the effects loop. Other gates I have used have consistently affected the sustain of my guitars especially on the clean channel, which matters to me. The ISP somehow does not do this. It's expensive but it works great.
One knob that does the trick.
Seems to be built like a tank.
This is expensive but it covers the front of the amp and effects loop which is the only way to get rid of all of the noise from a high gain amp.

I have tried several of the noise suppression devices out there and last one I bought (after returning this [*]) is MXR M-135 which I seem to be happy with. This G-String (which god knows why the heck they called it like that) is nothing but an adjustable gate that doesn't do it work faithfully. It actually adds noise on itself and does add a mechanical noise to accompany the tone. So guys, for those who need to understand what a noise gate does, it does not and cannot clean the noise. It can never distinguish noise from real tone. That is why the user sets a trigger to engage the gate. This G string, when it opens up the gate to let the guitar tone out it colors the noise too so the noise is like an envelope around the tone and stays after that, more pronounced like a snare drum's springs, very annoying and you cannot get rid of it. And btw, to get rid of the self hiss that this pedal injects, you have to crank that trigger even more and that clearly bites your tone down, but the envelope noise, just stays ever triumphant. I've tried it at the end of the chain, feeding off the other effects, and tried it in the effect's loop on the amp (VoX ac30c2x btw) and it was horrible. So guys, I am not sure about those who raved this one here. Maybe it works for them, but it's a bad noise suppressor! (I have a cheap digital multi effect with a noise gate that does a much better job than this [*]). Save your money and try other things until you are satisfied. Good luck.

Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

would replace this if stolen for sure. better than the hush units b ecause u dont have to reset for clean channel and limited drop off on sustain.
only one feature
does exactly what it sais quiets preamp noise and does not need to be reset for clean channel. this thing rocks!
a little pricey for a pedal but way cheaper than the rackmount. does its job to a T!

One of the Greatest pieces of gear to invest in!!!!

By Aaron Wirgau

from Romeo, MI

Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

The best... period.
This pedal is amazing! I run my Jackson SL3MG with EMGs into my Mesa Boogie Simul Class 2:90 power amp and this thing cuts down on any kind of noise or feedback that may get picked up in my signal to the amp. This thing does everything that they say it does! All other noise suppression pedals/ gates seem to affect your overall tone or has to be adjusted when you change from clean to dirty ect... This pedal does not. It stays consistent through and through. Invest in this pedal and you will be glad you did when you add it in to your rig!!

Perfect!!

Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

If you want an excellent noise gate that works perfectly in every sense, this is the one. Just set it up and forget it. I prefer quality equipment and am willing to pay for good products. After researching noise gates and reading several comments/reviews on the G String, it was the obvious choice. I have not been disappointed in the least. It is a permanent fixture on my pedal board. Highest recommendation.

Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

I set this unit up by itself with only my guitars and amp just to test it out. Guitar in, guitar out to amp. Then effects send into Decimator in, Decimator out to effects return. Adjusted the threshold until it was quiet, then played. I got tremendous feedback and squealing. Tried another guitar, same thing. Tried taking it out of effects loop, same thing. I don't know if mine was defective, but I tried to contact ISP for four days, had no response, and then I finally sent it back. It did not like the high gain on my Marshall amp. It would only work if I turned the gain down to about 5. What is the purpose of a noise reduction pedal if you can't use it on high gain?

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    I have a bunch of gear, a lot of tube heads, active/passive pickup guitars, pedals, rackmount gear.
    The G String manages to ajust to every amp or guitar.
    The only cons is that in a live performance if i have to exchange from a passive pickup guitar to an active pickup guitar i have to ajust the knob of the ISP. But if you stay with the same type of guitar pickups you have no trouble at all.
    Once you ajust the G String you forget you are using a Noise Gate.
    Fully transparent when adjusted correctly
    The reviews that say the pedal does not do their job properly or have wires and gear damaged... some people don´t know how to work with their own gear... sad but true

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    This pedal truly is the end of any guitarists search for a perfect noise gate. Offering a gate before the amp AND integrated into the effects loop is simply perfect. Having two gate loops is a must for any high gain tube amp, if you roll off the volume on your guitar then turn up the amps volume you can still hear white noise from the preamp. Connect a serial effects loop to the decimator and every, literally every noise except your guitar signal is gone. It tracks perfectly to fast notes and sustained notes. I even tried it played softly on a clean channel with the same settings and it sounded totally natural. Just set it and forget it. I'm pretty much convinced that the rackmount version of this is the same thing, just in a rack space. I don't think it's worth an extra couple hundred just for sticking it in a rack. Go with this one, it is the first purchase any guitarist needs to make.

    came with power supply. very shiny, pretty to look at. took some time to figure out where to put it in my chain of effects. turns out if you read the instructions that it is best used at the end of each chain of effects. so i got it after the ts9 on the front end and after my zoom multieffect unit in the effects loop. my tone stayed the same, and it successfully squashes all the noise coming from the amp. scary quiet, actually. my 6505+ has never sounded better. ive got it set at about 2 o'clock and my sustain is unaffected. buy it

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    I owned the ISP Decimator, but I didn't like how you had to turn it on and off when switching to a clean channel because it would cut everything off. The G String is a "Set it and Forget it" kinda pedal. But wait, there's more! It is natural sounding pedal, cuts noise just as promised. Solidly built too.If you are thinking of getting a Decimator, but are concerned is the extra money for a G-String worth it? Yes, yes it is. Unless you use only level of gain, or are in a studio.Only drawbacks is the 4 cable to get the best results, and also it still tracks a little funny when lowering the guitar volume pot low.

    Lives up to the hype

    By Paleolith54

    from Undisclosed

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    I play into a Boogie Express 5:25, known to be noisy on the Burn channel. Simply stated, this pedal eliminated the problem, with no negative impact on my tone, attack, touch-responsiveness, or sustain. Keep a couple of things in mind. 1. There are two basic set-ups. The first is to eliminate noise from your pedals you run in front of the amp. The second is to eliminate that noise PLUS the noise generated by your pre-amp. I am running the second set-up, and it works exactly as it should (you have to have an effects loop for this set-up). 2. Once you get around the point on the knob where all your noise disappears (mine is at around -40db), small movements make a noticeable difference in trade-off between noise reduction and tone/dynamics retention. My ideal setting is probably about -38 db (retain all tone/dynamics, very slight noise remaining). At and to the left of -40, too much noise. At and to the right of about -36 or so, playing is affected. If you like gain and are sick of putting up with noise, this pedal is an easy and effective solution.

    Great Pedal!

    By danulus

    from Bloomington, IL

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    Overall, I would highly recommend this pedal to anyone having problems with excessive noise in their signal chain--dependable, accurate, high quality.
    This product does exactly what it claims to do. It totally decimates the extra noise of my various effects and home circuitry as much or as little as I want. It follows my instrument very accurately and does not cause any notable loss of sustain. I am extremely pleased with the results and would highly recommend this product for anyone with several effects pedals. Yes, you'll need some extra cables as the cabling set up requires them--so I'd recommend purchasing 3-4 short cables to accommodate the system--but the results are well worth it!
    The unit seems of very sound and sturdy quality. No complaints.
    Overall value is great! For the kind of playing and recording I do, having this degree of noise filtering is essential and it compares favorably with rack-mount and other more expensive noise gates I've tried.

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    This noise gate is the best one avalible in pedal form, period. And not by a slim margin-- it is leagues above the rest. For anybody using a lot of gain or distortion, this unit cannot be beaten. I use a boss metal zone into a marshall JVM. This pedal, when connected properly, allows my amp to become completely silent in between songs. So silent that it sounds as if the amp is in standby mode. And yes, the first thing you will want to know is if it is transparent or ruins your sound.. It does not. I now consider this pedal absolutely essential.

    from Undisclosed

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    I know what your thinking, and yes, I agree, very expensive pedal, but I could not even tell how amazing this thing works. The features are awesume. Being able to run your pedal to the effects loop and to the front of the amp is extremely helpful. If you absolutely hate feedback ( especially during break downs like I do ) then this is the pedal for you. The amp im running right now is a peavey triple X, and its a Gain and feedback monster but the decimator g-string tames it completely without even slightly effecting my tone. OH, don't worry about shuting it off when you switch to clean either cause it doesnt cut your clean sustain. I actually laughed the first time I used it cause its that good. Defeintly check it out, you won't regret it.

    Problems:

    ISP really dropped the ball with clear instructions. If you are just using this for the guitar feed back, not your amp hum or to quiet your fx loop. Do not buy this just get the standard decimator.

    HELP:

    Decimator not working for just guitar??

    If you plug straight into the guitar in/out direct to your amp. IT WON'T Work. You need to patch the open connections for it to work.

    Plug guitar into the "Guitar In" and Plug the "Dec out" To your amp. Get a jumper cable and patch "Dec In" To "Guitar out" and it will work for just guitar.

    To use in your FX loop with mod effects Plug guitar into "Guitar In" and "Guitar out" goes to your amp's input. The "Dec out" goes to the "in" on the first mod pedal (delay, verb) in your FX loop pedal chain. The "out" on the last pedal in your loop goes to the "return" on your amp's fx loop. The send from your FX loop goes to the "Dec In". Your done! bam! If you are using time based effects make sure they are true bypass and you have "dry kill" off!!!

    The Good:

    I am endorsed by Jet City and run a JCA100 live. The thing cranks! Sounds like a 5150 but it's noisy noisy noisy! The G string fixed the amp noise and I mean amp noise not Guitar noise! If you turn your volume down on the guitar and have a hum it's your amp! My amp is virtually silent on the heaviest gain settings now! I had no idea this could be done. Just run two cables in the fx loop then use the guitar in/out for guitar. I am so happy with the decimator worth every penny!!

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    My friend turned me onto to ISP while I was using my Boss NS-2. The Decimator works WAY better. Plus when using the Decimator G pedal, I don't need to run a separate pedal up front. The Decimator G will run up front and through your effects loop cutting out the 'waterfall' sound that high gain amps get. This thing works great with my Diezel "Herbert" head. Worth the price! I would say if you have a little extra money, get the Decimator ProRack G. It's more expensive but is by far the best noise reduction system out there.

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    I was looking into noise gates on a forum I browse and this one always came up so I looked it up and the reviews were all steller. So I bought it and I am not disappointed in the least. I was going to buy the regular decimator but I am sure glad I paid more for this because it is totally worth it. I never turn it off and my 5150 II doesn't make a peep anymore no matter what I do. Once I found the balance of good clean gating and my lead tone that was it, I haven't touched it since. If you are looking for an incredible noise gate for a high gain amp with an FX loop then don't look anywhere else, this is it.

    Disappointed

    By Souldog

    from Paducah, Kentucky

    See all my reviews

    Comments about ISP Technologies Decimator G String Noise Reduction Guitar Effects Pedal:

    After reading the other reviews, I can only conclude that I received a defective pedal. The Decimator G String did nothing but add noise. It added noise when it was on and when it was off. It added noise whether used directly between guitar and amp ('52 Hot Rod Tele and Mesa amp) or through the effects loop. I tried before and after pedal board, as well as without pedal board. I replaced batteries and tried direct power, all to no avail. This is particularly disappointing since I went with the higher priced pedal based on negative comments from users of less expensive units.

    The only good news was that Musicians Friend made it easy to return.
