ISP Technologies introduces the revolutionary patent pending HUM EXTRACTOR™ + DECIMATOR G, two channel, ultimate noise reduction system. After years of musicians fighting the major noise problem of power line frequency hum, ISP Technologies eliminates this dreaded noise with the new patent pending HUM EXTRACTOR™. Power line frequency hum is most commonly caused by stray magnetic fields generated from transformers or power lines in close proximity to the instrument pickups. While Hum Bucking pickups have been in use for years to help reduce this problem, if the level of hum is severe, even Hum Bucking pickups are not enough and many players still prefer the sound quality and tone of single coil pickups.

ISP Technologies introduces the new DECI-MATE G™ Micro Decimator pedal. The DECI-MATE G pedal is a full implementation of the world renowned Decimator G circuit with new patent pending tracking improvements all in a small, micro pedal package. When real estate is critical the DECI-MATE G is the answer. Now you can have the best noise reduction available in a micro pedal package with the full functionality of the larger G version of the Decimator pedal. The DECI-MATE G has a loop to insert your noisy pedals or connect to the effects loop of a guitar amplifier that has a series loop. The G version of the Decimator allows the noise reduction to directly track the guitar output. The advantage of tracking the direct guitar is the noise floor of the direct guitar output remains constant when you switch pedals or preamplifiers with different gain settings. This allows the DECI-MATE G to eliminate the noise in your rig without any need to adjustment it’s threshold setting for different gains and the corresponding noise floor changes. You can switch between extreme high gain and clean and never need to adjust the threshold. The ISP Technologies engineering team has spent years perfecting the operation of real time noise reduction and has been awarded multiple patents for the Decimator Technology. Patents include the technology for the adaptive response of the Decimator, which tracks the envelope of both super fast staccato notes as well as long sustained notes.

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.

If you want the ultimate in electric guitar noise reduction: ISP's Decimator II G String.

ISP's Decimator II noise gate guitar pedal ups the ante over the original Decimator design to give you even better noise reduction.

ISP Technologies presents the latest generation in high performance Noise Reduction technology, the DECIMATOR™ PRO RACK DUAL CHANNEL NOISE REDUCTION SYSTEM. From the original inventors of the HUSH® noise reduction comes the latest, most advanced, patent pending, state of the art technology in real time noise reduction. The Decimator offers a revolutionary breakthrough in Noise Reduction processing with an unparalleled level of performance. The HUSH system, as well as all other noise reduction systems suffers from one major problem inherent in their design: The system cannot be immediately responsive to both very short-term staccato notes and long slowly decaying signals. The typical downward expander noise reduction system suffers from a dead zone in the release response characteristic, which causes a compromise in tracking both fast decaying notes and long sustained notes.Say something interesting about your business here.
