ISP Technologies introduces the Decimator II, second generation of the Decimator Noise reduction. The Decimator II includes improved performance and innovations so unique that it is covered under two new patents pending for these new innovative improvements.

The Decimator II also features improvements in the expander tracking with ISP's new Linearized Time Vector Processing. This novel improvement provides a more linear release time-constant response for the exponential release curve of the downward expander. While the expander is exponentially increasing expansion and dynamically changing its response to fit the envelope of the input signal, the release response remains linear over a given time period. This increases the smoothness of the release response of the expander and provides the most transparent release response of any noise reduction system available and virtually eliminates any release ripple for incredibly smooth decay of longer sustained notes.

The ISP Decimator II includes a LINK IN and LINK OUT allowing two pedals to be linked via a common 1/8 inch Tip/Sleeve or Tip/Ring/Sleeve phone cord allowing both pedals noise reduction signal processing circuits to track the direct instrument input. With two Decimator II pedals linked you will get close to the same level of performance available in ISP's professional Decimator ProRack G system in pedal form. This allows you to use one block of Decimator between the guitar and input of the amplifier, a second in the effects loop, use dual preamps in a system with a Decimator II after each pre-amp, or implement true stereo noise reduction systems using this link connection. Using the LINK function between two pedals allows a number of options. By using a standard Decimator II between the guitar and the input of the guitar rig and a second standard Decimator II inserted into the effects loop, you can achieve the same basic performance of the professional Decimator ProRack G.

Things You Will Get:

    Effect Pedal

Must have this in every pedal board


This thing speaks for itself. Don't want noise? Get this! The quality is top notch.



What?? nothing!


Easy silence.. Turn it on, dial it in, and enjoy the complete silence. Always on in my loop.



Best Noise Reduction


I use this in front of my amp. I have tried a lot of noise gate pedals, this one works really well. I use it for when I have a few pedals on at the same time, takes away the white noise from compressor pedal into distortion into delay. Does not cut my sustain abruptly off, like some of the others did. I try a lot of different pedal configurations on at the same time, and this works extremely well at keeping the noise away. Very pleased with it.




Love it. Works just as it says. Delivery time was fast.


I use it in my effects loop to cancel out preamp noise from hi gain head. Works perfectly to do this.
