The general configuration is simple, in terms of branches inside is very explicit.

In my case I branch and

1-Gibson les paul custom black


Came in 3-channel 1 isp

4-Out isp to slash afd amp head

5-Out effect to in isp

6-Out isp to know and effects in order:

Empress Compressor 6.1

6.2 Empress Tremolo

6.3 Tc electronic dreamscape

6.4 Empress delay

6.5 Volume Pedal Boss

7 - Back to the effects in the afd

The edition of the rack is simple, just a button channel.


The noise gate is powerful, no noise. When you stop playing you put your left hand on the ropes.

The volume pedal to me is very useful.

The red LED in front of his nice, I put my isp between two cabinets 1960.

Buttons on the back allow you to adjust the noise gate, or in fact it should be applied. Unfortunately for me, I came across a seller very honest with me sent with a knob at the back hs.


Can I use it for

The value for money is ok if you want to have quality.

Yes I recommend this choice, you watch the video's on you tube, this is true even better.

Isp Technologies Decimator ProRackG
1U sound suppressor 19 '.

Jack connections are 6.35, mono input and output.

People ISP (in fact, it is those who had the cr Systm Rocktron Hush home) dvelopp have what they call the Time Vector Processing ... wholesale processor DTECT the signal just scratching the APRS and automatically applies SETTING THE decay to two channels ... and more problem of rglages between saturated and clean channels!

For the record, j'tais about to buy a Quad Noise Gate Drawmer from home, with 4 channels spars. I wanted to use just one channel APRS guitar, 1 channel for clean sounds and one for the full, the last 2 as automatically selected by switch my GRX-4. Thanks to the Decimator, I played a sore head in the final simplicity and even cash!


It's like razors with multiple blades, THE FIRST soulve the hair and cut deuxime: Well the password THE FIRST eliminates parasites output guitar (buzz, hum mass , single coil pickup, parasites, in short, it can get crowded!), and deuxime must eliminate the breath out of pramp, or unwanted feedback between the notes cheeks. I say "must eliminate" because indpendants both channels, you can also use it as a noise gate in Stereo output pramp, o l o well want in your cha no sound. But it is clear that the system does not work then Manir optimal.

You have to SETTING THE each channel of an on / off button, a knob for level rgler o you want to cut, with 3 LEDs to display the level of the cut, and a button s selection of the signal level of (-10dB or +4 dB). In addition, a dynamic filter knob you can (on two channels at the same time), move the range frequency drives for all your rglages.

In short, it's super simple!


I first made this: Guitar -> Decimator Channel 1 -> Preamp clear sound background -> background sound
I put the knob of attnuation bottom, and I went back down until hearing the buzz and other background noises. I started just above, to no longer have them.

Then I added (with pramp This time in saturated: pramp background -> Dcimator channel 2 -> background sound.
And ditto for the rglage. I ended up with a blast of near-zero output, and when I plated G chord, the cat of my neighbors became deaf, and I have lost 10 dB each ear ...

So great a work, then I pass into sound clear and everything is moving, is to say:
- No wind output
- The mug is saturated all the notes, you really have to wait for an agreement plate is caught by the buzz or shot by the noise-gate (the time is suprieur I can be Amen to live)
- In its clear notes do well, no effect type "battery use", where 4 is a note on food (except of course if you set the level of the ax ...)


I have not tried the Hush, I had one until the Boss NS-2, walking a lot ... but we change the CATEGORY. There are no frills, it achte to remove any sound other than his own, and after 5 minutes it's done, and done really well.

Here is an innovation that is good for all guitarists demanding for their sounds!

Isp Technologies Decimator ProRackG
View previous opinion, is fairly well explained.

Basically, there is a channel to put between the guitar and amp (or the first pedal used) and a second set after the amp (so it's the first effect of the loop).


Pretty simple really once you made the right connections.
Just set the input level of each channel (I put the first 4 and -10 for the second) and then adjust the level of the gate for each channel.
Finally, we define the level of the tracking filter that changes the sound a bit better but makes the dynamics in my case (to about -3 for me).

There are even 3 small switches on the back to simply remove the ground noises and other problems related to electrical installation where it connects.


Superb very transparent. Noise reduction and noise.
I love it. Every guitarist should own one so you can enjoy even more music being played quietly side.


I used the decimator pedal in front and frankly we turned a corner with the rack model nothing to say except that it's expensive. even very expensive.

However, this choice I would do without hesitation because there is no real equivalent for me.
