ISP Technologies Hum Extractor Plus Decimator Guitar Pedal

Musicians have battled power line frequency hum for decades, but ISP Technologies has cracked the code with their groundbreaking Hum Extractor™ + Decimator G system. This revolutionary two-channel noise reduction processor tackles the persistent problem of stray magnetic fields from transformers and power lines that plague guitar pickups, offering a solution that goes beyond traditional hum-bucking pickups whilst preserving the beloved tone of single coil pickups.

The system’s patent-pending Hum Extractor technology achieves what was previously thought impossible – completely removing power line hum without compromising your instrument’s natural tone and sonic character. Unlike conventional noise gates that only work effectively at high gain settings, this DSP-based processor eliminates hum across all playing dynamics, from pristine clean tones to heavily saturated leads. The flexible design allows the Hum Extractor to operate in either channel based on your rig configuration.

Beyond hum elimination, the unit incorporates advanced Decimator X technology with adaptive release characteristics, plus a third noise reduction function featuring high-frequency sliding filtration borrowed from ISP’s professional rack processors. The intelligent system uses the direct guitar signal (post-hum removal) for level detection, ensuring precise tracking and superior noise reduction of gain-related hiss and unwanted frequencies. With 32-bit floating point DSP processing and premium A/D/D/A converters, the Hum Extractor + Decimator G maintains audiophile-grade signal integrity whilst providing unprecedented real-time noise control for serious musicians.
