ISP’s Ultimate Noise Reduction Pedal

Get to know them!

No matter how noisy your guitar rig is, the ISP Technologies Hum Extractor + Decimator G pedal will make it whisper-quiet. This 2-channel noise reduction system boasts both a high-quality hum extractor and Decimator X noise suppression, empowering it to eradicate the full gamut of performance-wrecking sonic artifacts. Like ISP’s Decimator G-String models, the Hum Extractor + Decimator G tracks directly from your guitar’s signal — no more cut off notes when you switch from high-gain to clean tones. And every parameter of this pedal is customizable, enabling you to tailor it to your rig and application while guaranteeing transparent results. The Hum Extractor + Decimator G is ISP Technologies’ ultimate noise reduction pedal. And given ISP’s track record of success on that front, that’s saying a lot! If you want to add a pro-level noise suppression system to your guitar rig, the Hum Extractor + Decimator G gets our top recommendation.

2-channel design provides superior instrument tracking

The Hum Extractor + Decimator G’s 2-channel design gives you the power and versatility of the Decimator’s loop gating while still being triggered via the direct output of your guitar. This means you can insert the Hum Extractor + Decimator G into, for instance, the effects loop of your amplifier to filter out noise from everything prior to the power amp and speakers — dirt boxes, vintage stomps, and even your tube amp’s preamp section — to absolutely obliterate unwanted noise. This gives the Hum Extractor + Decimator G superior instrument tracking for country as well as metal and intense noise reduction for demanding studio applications.

Wide range of controls for maximum configurability

The ISP Hum Extractor + Decimator G includes a wide range of controls that enable you to fine-tune the noise reduction system to your rig. An Input Gain knob and Input Level meter safeguard against out-of-whack signals, while a Loop Clip indicator make level-matching the pedal to your amplifier and other gear easy. Separate Hum Extractor + Decimator G and Decimator Threshold knobs tailor the amount of processing for each type of noise reduction, while an HX Position switch allows you to choose where you want to place the pedal’s hum extraction — directly after your guitar or in your effects loop. The Hum Extractor + Decimator G is one of the most advanced noise reduction pedals we’ve seen here at Sweetwater. It could easily replace a high-dollar rackmount unit.

Decimator X technology offers ultra-transparent performance

If you play through a high-gain amp, then noise reduction solutions can be frustrating. Typical noise gates chop off your notes, while more sophisticated digital options can compromise your tone. Thanks to Decimator X technology, the Hum Extractor + Decimator G avoids both of these predicaments. It employs vector integration, which supplies you with flawless adaptive release times. The result is smooth releases, regardless of your playing style. Lightning-fast staccatos? No sweat. Sustained legatos? No problem. With the Hum Extractor + Decimator G on your pedalboard, you'll hear nothing but silence between your short riffs, and chopped-off sustained phrases will become a thing of the past.

ISP Technologies Hum Extractor + Decimator G Features:

  • Packs a transparent hum extractor and Decimator X noise suppression into a single pedal
  • Tracks directly from your guitar's signal
  • Hum Extractor employs a dynamic filter and downward expander to make short work of 50Hz or 60Hz hum (selectable)
  • Decimator X noise suppression suits rapid-fire staccato riffs as well as long, sustained phrases
  • Input Gain knob and Input Level meter safeguard against out-of-whack signals
  • Loop Clip indicator make level-matching with your amp and gear easy
  • Separate Hum Extractor and Decimator Threshold knobs tailor the amount of processing for each type of noise reduction
  • HX Position switch allows you to choose where you want to place the pedal’s hum extraction
  • Superior to traditional noise gates — won't chop off sustained notes
