Description

When noise threatens to overshadow your musical brilliance, the ISP Technologies Hum Extractor + Decimator Noise Reduction System steps in as your silent guardian. This dual-channel powerhouse is designed to tackle the notorious power line frequency hum with ease, thanks to the patent-pending Hum Extractor technology. It's the perfect ally for guitarists who crave the pure, unadulterated tone of single-coil pickups but dread the accompanying noise.

The Hum Extractor + Decimator system doesn't just stop at hum removal. It incorporates the celebrated Decimator X noise suppression to ensure your riffs remain crisp and your sustains smooth, even through high-gain setups. Unlike traditional noise gates that rudely cut off notes, this pedal uses advanced vector integration to deliver adaptive release times, preserving the integrity of your performance.

With intuitive controls, including separate knobs for Hum Extraction and Decimator thresholds, you can fine-tune your rig to perfection. The HX Position switch offers placement flexibility, while the Input Gain knob and Level meter keep your signals in check. Whether you're taming a vintage amp's roar or insulating your rig from modern interference, this pedal ensures you can focus on what matters most: your music.
